UCRL 179 Car~_,_ ...... TABLE OF· .THE ISOTOPES. G. T. Seaborg and I. ;E?erlman !' Department of Chemistry- and Radiation Laboratory University of Daiifornia Berkeley, California . August, 1948 The compilation of this table was sponsored by the Atomic Energy Commission • • . ~ TABLE (#F THE ISOTOPES · G. T. Seaborg and I. Perl.Dan ~partment· of Chemistry and Badiati-<;>n Laboratory University of California, Berkeley, California The following table represents a complete list Qf all the artifioi~l and Datura! radioaoti ve isotopes and stable isotopes, together .with. a number of their·impc)r.tant features oo:vering information available by approximately July, 1948, through publications, privat~ communications and almoiJt all of the restricted distribution repo~ts of the U~ s. Atomic Energy Commission, the foriler "Manhattan District", U. s. Army Corps· of Engineers _and the corres ponding offices of Great 'Britain and CaDada. W-i'hll very fp exceptions the· ori ter~on for listing a radioactive isotope ha's been the actual obsenation of its radiation. · · The first Qolumn lists the atomic numben and maas numbers of the iso topes. The. s·u~rsoript "m" foll~ing the mass number denotes a metaatabl• isomer of measured half-life. of either a stable or una table ground state but the isomeric transition Qeed not have been observed. In the second column hea~ed "class" the degr~e of oertaint,y of ·each isotopic asa'ignment. is ind\oated wi-th a· letter according to the following oodes · ·A • isotope certain {mass number and element certain) B • isotope probable, element certain . C • one of few isotopes, el~nt certain D • eleme~~t certain· B • element probable· .F • insufficient evidence . ' In JIOst oases the class ia. determined by evaluating the uniqueness of. the assignment through ohanica-1 aepara"tion, reaction type and yield· con siderations, genetic relatio~s~ips, ana type of ~adiation. In a few oasea newer techniques have been used.. The term ."m.s." in the eeoond columi i'eters to the identification of the ••s number by meana ot a ••s ~pectro graph, and "rea.n.aot.·" {resonance neutron activation) refers to the 1clen- · · tification of a nuclear is0111er by· obHrring 11oth iso•r• upon irradiation with til tered neutrons •.. With the mas <8pectrographic assigmaent ol' ••• huabera there are ·acme instances in whioh the maaa nUilber ta ~with greate_r certainty than. the eleaent. · .Such oases are tlsai~ecl the appNpria11e code l~tter .auoh as •1• followed by •a.a.•. · fhe percent abuDdance of the atable hotopes is liited in colUIID three. !he fourth colWID lists 1he type of radiation, with the following •an- ing tor the symbolst ~= •negatiYe beta-particles (negatrons) ~ • positive beta-particles (positrons) Y • guma-rays 4 • alpha-particles n • neutrons e- • internal-conversion electrons K • 1:-electron capture (or in more general tei"JIIS, orbital electron capture) I.T.• isomeric transition (transition from upper to lower isomeric state) In the oases where it is certain that no gauma-rays are emitted, this tact 1e expressed explio itly in column seven by the term •xo Y". Ann!hilation galllllll-rays and x-rays are not listed. It my 'be assumed that x-rays han been observed or aotOa,lly identified in almost all oases of orbital e~ectron capture listed. !he halt-life, followed 'by the relevant reterenoe, is ginn in the fifth column. In moat oases the determination is direct, either by aeaaur ing the decay rate, by weighing a long-lived isotope of known purity,·or by comparing the aothity with that of a genetically related isotope of known halt-lite.' A nUDtber of halt-li vea are known only from the yield ot activity resulting from a nuclear reaction of known or estimated croas eeotion. Halt-Uvea estimated in this -.nner are indicated by the tena "yield". Usually tor the oases where more than one value for the half'- · life has been reported, an attempt has been !U.de to list the beat 'Value (an experimental value. thought to be taken under th• moat favorable condi tions) rather tilan a mean value; more 'than one 'ftlue is u.ated where a ohoioe does not seem obvious. Among tile natural radioactivities an average value is often used which was taken from an interaatioml OOIIDllittee slDIIlB.ry report (060). In the columns headed "energy of radiation•, the energy value is fol lowed by the corresponding reference and by a description ot the method uaed tor the energy determination. The beta-particle energies correspond 'tQ the observed upper limits of the spectra, 'in those oases where onl7' the Jronopinald-Uhlenbeok (1:32) extrapolated 'ft.lue has been reported, this 1e listed, followed by the designation •x.u.•.

(~-, ~+, a, K or I.T.) f'or the radioactivity. !he observed nuclear reactions (giving the target element, projectile and outgoing particle, in order) by which the radioactive isotopes are formed, and the corresponding references are listed in the last column (p =proton. n =neutron, a= alpha-particle, d = deuteron,_t • tritium or triton (H3), y • ~amma-ray, e- • electron). In -cases in which the target material is not the naturally occurring element but one enriched or depleted in a particular isotope, that isotope is indicated! No means for identify ing the source or energy of the projectile is given. For example, deuterons varying from low energies to 200 Mev have been used. In many oases,. with high energr projectiles, multiple particles are ejected& A reaction such as (d-ap2n) is a formal presentation showing what the outgoing particles might be and does not mean that the order of leaving the nucleus was de termined nor that the a., p and n were identified. I . In some cases where the .path for reaching the product nucleus can e-ven, less definit~ly be stated the reaction is presented -in the form _(d-3zl0a) , _ where "3z" indica-tes that the product nucleus is lower in atomic number than the compouild nucleus by- three units and "lOa" means that it is lower in mass· number l?Y ten units. Where the same isotope has been made by spallation of various target elements with high energy tarticles this is indicated by the symbol "spal." followed by the symbols for the target elements. Stable product nuclei which have been identified by means of the mass spectrograph are indicated by "m.s." following the reference. The neutron .... !"'. induced fission reactions of the heavy elements are designated by such· symbols as U-n, Th-n, Pu-n and Pa-n, while the ~amma-ray, deuteron and_. alpha-particle-induced fission reactions are designated by symbols such as U-Y • U-d, and u-a.. Usually, but not always, "U-n11 will mean the slow neu tron fission of U235 while "U-d" or 'U-a" desi,;nated fission products arise from U238. In this last column the method of production f'o.r each radio active fission product is described by these symbols (U-n, etc.) together with the designation of its radioact.ive parent and its radioactive daughter when these are known. Similarly, for the radioactivities of' the heavy natural and artificial families there are listed the immediate parent and daughter isotopes. The natural radioactivities without parents are listed as produced by a "natural solu-~e", followed by a reference to the discovery. Some of the data entered in tliis table were taken from restricted -.., ) distribution reports which are not generally available. These have reference ~umbers from 100-199. References to the open literature have numbers below 100 or over 200. No attempt has been made to list all of the ·publications OP restricted distribution reports 'connected with a given radioactivity since it has been the aim to keep the table as compact as possible. As a rule references to the original papers are not given when better data are avail able in more recent publications. The references which are listed usually give a key to the complete literature. Those references designated by "NNEB-PPR" refer to papers which will appear in the forthcoming National Nuclear Energy Series - Plutonium Pro ject Record. Similarly, the symbol "AECD" refers to a declassified u. S-• Atomic Energy Commission Document bearing the indicated number.
