The rapid neutron-capture process, or r-process, is known to be of fundamental importance for explaining the origin of approximately half of the A > 60 stable nuclei observed in nature. Recently, special attention has been paid to neutron star (NS) mergers following the confirmation by hydrodynamic simulations that a non-negligible amount of matter can be ejected and by nucleosynthesis calculations combined with the predicted astrophysical event rate that such a site can account for the majority of r-material in our Galaxy. We show here that the combined contribution of both the dynamical (prompt) ejecta expelled during binary NS or NS-black hole (BH) mergers and the neutrino and viscously driven outflows generated during the post-merger remnant evolution of relic BH-torus systems can lead to the production of r-process elements from mass number A > 90 up to actinides. The corresponding abundance distribution is found to reproduce the∼ solar distribution extremely well. It can also account for the elemental distributions observed in low-metallicity stars. However, major uncertainties still affect our under- standing of the composition of the ejected matter.

Even though Yarious theoretical methods have been suggested, based upon the particular aspects of experimental results, it has been impossible to find a successful theory which suffices to explain the whole observed properties of atomic nuclei. In 1936, Bohr (J, P• 344) proposed the liquid drop model of atomic nuclei to explain the resonance capture process or nuclear reactions. The experimental evidences which support the liquid drop model are as follows: 1. Substantially constant density of nuclei with radius R - R Al/3 - 0 (1) where A is the mass number of the nucleus and R is the constant of proportionality 0 with the value of (1.5! 0.1) x 10-lJcm~ 2.

  • CHAPTER 2 the Nucleus and Radioactive Decay
    1 CHEMISTRY OF THE EARTH CHAPTER 2 The nucleus and radioactive decay 2.1 The atom and its nucleus An atom is characterized by the total positive charge in its nucleus and the atom’s mass. The positive charge in the nucleus is Ze , where Z is the total number of protons in the nucleus and e is the charge of one proton. The number of protons in an atom, Z, is known as the atomic number and dictates which element an atom represents. The nucleus is also made up of N number of neutrally charged particles of similar mass as the protons. These are called neutrons . The combined number of protons and neutrons, Z+N , is called the atomic mass number A. A specific nuclear species, or nuclide , is denoted by A Z Γ 2.1 where Γ represents the element’s symbol. The subscript Z is often dropped because it is redundant if the element’s symbol is also used. We will soon learn that a mole of protons and a mole of neutrons each have a mass of approximately 1 g, and therefore, the mass of a mole of Z+N should be very close to an integer 1. However, if we look at a periodic table, we will notice that an element’s atomic weight, which is the mass of one mole of its atoms, is rarely close to an integer. For example, Iridium’s atomic weight is 192.22 g/mole. The reason for this discrepancy is that an element’s neutron number N can vary.

  • Chapter 2: Atomic Systematics and Nuclear Structure
    2 ATOMIC SYSTEMATICS AND NUCLEAR STRUCTURE In this chapter the principles and systematics of atomic and nuclear physics are summarised briefly, in order to introduce the existence and characteristics of isotopes. 2.1 ATOMIC STRUCTURE AND THE PERIODIC TABLE OF THE ELEMENTS Atoms consist of a nucleus surrounded by electrons. Compared to the diameter of an atom, which is of the order of 10-8 cm, the size of the nucleus is extremely small (~ 10-12 cm). The dense concentration of matter of the nucleus mainly consists of two kinds of particles, neutrons and protons, which have about the same mass. The neutron carries no electric charge, while the proton is positively charged. The number of protons (Z), the atomic number, is equal to the number of electrons surrounding the nucleus. Electrons have a mass that is about 1/1800 that of the proton mass and carry an equal but negative electrical charge, so that the atom as a whole is neutral. Atoms missing one or more electrons are referred to as positive ions, atoms with a number of electrons exceeding the atomic number are called negative ions. Protons and neutrons, the building stones of the nucleus, are called nucleons. The sum of the number of protons and neutrons (N) in a nucleus is the nuclear mass number: A = Z + N (2.1) The notation describing a specific nucleus (= nuclide) of element X is: A Z XN Because the chemical properties of an element (X) are primarily determined by the number of electrons in the atom, the atomic number Z characterises the element.

  • Polytopes and Nuclear Structure by Roger Ellman Abstract
    Polytopes and Nuclear Structure by Roger Ellman Abstract While the parameters Z and A indicate a general structural pattern for the atomic nuclei, the exact nuclear masses in their fine differences appear to vary somewhat randomly, seem not to exhibit the orderly kind of logical system that nature must exhibit. It is shown that separation energy [the mass of the nucleus before decay less the mass of a decay’s products], not mass defect [the sum of the nuclear protons and neutrons masses less the nuclear mass], is the “touchstone” of nuclear stability. When not part of an atomic nucleus the neutron decays into a proton and an electron indicating that it can be deemed a combination of those two. Considering that, the nucleus can be analyzed as an assembly of A protons and N = A - Z electrons, where N of the protons form neutrons with the N electrons. Resulting analysis discloses a comprehensive orderly structure among the actual nuclear masses of all the nuclear types and isotopes. The analysis examines in detail the conditions for nuclear stability / instability. An interesting secondary component of that analysis and the resulting logical order is the family of geometric forms called polytopes, in particular the regular polyhedrons.
