  • 12 Natural Isotopes of Elements Other Than H, C, O
    12 NATURAL ISOTOPES OF ELEMENTS OTHER THAN H, C, O In this chapter we are dealing with the less common applications of natural isotopes. Our discussions will be restricted to their origin and isotopic abundances and the main characteristics. Only brief indications are given about possible applications. More details are presented in the other volumes of this series. A few isotopes are mentioned only briefly, as they are of little relevance to water studies. Based on their half-life, the isotopes concerned can be subdivided: 1) stable isotopes of some elements (He, Li, B, N, S, Cl), of which the abundance variations point to certain geochemical and hydrogeological processes, and which can be applied as tracers in the hydrological systems, 2) radioactive isotopes with half-lives exceeding the age of the universe (232Th, 235U, 238U), 3) radioactive isotopes with shorter half-lives, mainly daughter nuclides of the previous catagory of isotopes, 4) radioactive isotopes with shorter half-lives that are of cosmogenic origin, i.e. that are being produced in the atmosphere by interactions of cosmic radiation particles with atmospheric molecules (7Be, 10Be, 26Al, 32Si, 36Cl, 36Ar, 39Ar, 81Kr, 85Kr, 129I) (Lal and Peters, 1967). The isotopes can also be distinguished by their chemical characteristics: 1) the isotopes of noble gases (He, Ar, Kr) play an important role, because of their solubility in water and because of their chemically inert and thus conservative character. Table 12.1 gives the solubility values in water (data from Benson and Krause, 1976); the table also contains the atmospheric concentrations (Andrews, 1992: error in his Eq.4, where Ti/(T1) should read (Ti/T)1); 2) another category consists of the isotopes of elements that are only slightly soluble and have very low concentrations in water under moderate conditions (Be, Al).

  • Nuclear Lattices, Mass and Stability
    Open Access Library Journal Nuclear Lattices, Mass and Stability Henry Gu Cao, Zhiliang Cao, Wenan Qiang Northwestern University, Evanston, USA Email: [email protected] Received 20 April 2015; accepted 7 May 2015; published 13 May 2015 Copyright © 2015 by authors and OALib. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract A nucleus has a lattice configuration, a mass, and a half-life. There are many nuclear theories: BCS formalism focuses on Neutron-proton (np) pairing; AB initio calculation uses NCFC model; SEMF uses water drop model. However, the accepted theories give neither précised lattices of lower mass nuclei, nor an accurate calculation of nuclear mass. This paper uses the results of the latest Unified Field Theory (UFT) to derive a lattice configuration for each isotope. We found that a sim- plified BCS formalism can be used to calculate energies of the predicted lattice structure. Fur- thermore, mass calculation results and NMR data can be used to determine the right lattice struc- ture. Our results demonstrate the inseparable relationship among nuclear lattices, mass, and sta- bility. We anticipate that our essay will provide a new method that can predict the lattice of each isotope without the use of advanced mathematics. For example, the lattice of an unknown nucleus can be predicted using trial and error. The mass of the nuclear lattice can be calculated. If the cal- culation result matches the experimental data and NMR pattern supports the lattice as well, then the predicted nuclear lattice configuration is valid.

  • Explorations of Magnetic Properties of Noble Gases: the Past, Present, and Future
    magnetochemistry Review Explorations of Magnetic Properties of Noble Gases: The Past, Present, and Future Włodzimierz Makulski Faculty of Chemistry, University of Warsaw, 02-093 Warsaw, Poland; [email protected]; Tel.: +48-22-55-26-346 Received: 23 October 2020; Accepted: 19 November 2020; Published: 23 November 2020 Abstract: In recent years, we have seen spectacular growth in the experimental and theoretical investigations of magnetic properties of small subatomic particles: electrons, positrons, muons, and neutrinos. However, conventional methods for establishing these properties for atomic nuclei are also in progress, due to new, more sophisticated theoretical achievements and experimental results performed using modern spectroscopic devices. In this review, a brief outline of the history of experiments with nuclear magnetic moments in magnetic fields of noble gases is provided. In particular, nuclear magnetic resonance (NMR) and atomic beam magnetic resonance (ABMR) measurements are included in this text. Various aspects of NMR methodology performed in the gas phase are discussed in detail. The basic achievements of this research are reviewed, and the main features of the methods for the noble gas isotopes: 3He, 21Ne, 83Kr, 129Xe, and 131Xe are clarified. A comprehensive description of short lived isotopes of argon (Ar) and radon (Rn) measurements is included. Remarks on the theoretical calculations and future experimental intentions of nuclear magnetic moments of noble gases are also provided. Keywords: nuclear magnetic dipole moment; magnetic shielding constants; noble gases; NMR spectroscopy 1. Introduction The seven chemical elements known as noble (or rare gases) belong to the VIIIa (or 18th) group of the periodic table. These are: helium (2He), neon (10Ne), argon (18Ar), krypton (36Kr), xenon (54Xe), radon (86Rn), and oganesson (118Og).

Data taken show that between eighteen and twenty-five percent of the neutron counting efficiency is lost when using low-level discrimina- tion of 100mV, per manufacturers recommendation. Also, the charge-coupled amplifiers of the detectors may be responsible for changing the pulse height distributions of the detectors. Keywords: He-3 detectors, safeguards monitoring, low-level discrimination, counting effi- ciency ACKNOWLEDGMENTS When it comes to making my Physics education a success, three people deserve utmost honors and recognition.

Cross sections for 6He, 7−9Li, 10−12Be and 14B nuclei on 28Si, 181Ta and 59Co targets were measured at 10 – 60 MeV u−1 energy range using modified transmission method. In total, 120 cross sections were extracted. The purpose of the experiment was to investigate an unexpected behavior of cross sections found in certain exotic nuclei. Especially of interest was a sudden growth, observed in heavy helium and lithium isotopes at low energies. These features are presumably manifestations of a halo and cluster-like structures in these nuclei. Obtained results may yield relevant data for the development of more accurate microscopic nuclear models and radiation resistant electronics. In this work, a detailed description is given of the measuring setup and the methods used in the experiment. Keywords: exotic nuclei, total reaction cross section, cross section, halo, neutron halo, proton halo, cluster 4 Tiivistelmä Louko, Jussi Keveiden eksoottisten ytimien kokonaisvaikutusalojen mittaus Pro gradu-tutkielma Fysiikan laitos, Jyväskylän yliopisto, 2019, 51 sivua Tässä pro gradu-tutkielmassa perehdytään kokeeseen, jossa eksoottisten 6He, 7−9Li, 10−12Be ja 14B ytimien vaikutusaloja 28Si, 181Ta ja 59Co kohtioihin, mitattiin 10–60 MeV u−1 alueella.
