A study of nuclear structure for Am-244, Pu-238, Po-210, Pm-147, Cs-137, Sr-90 and Ni-63 nuclei used in nuclear battery

摘要

In this paper, we intend to extend the nuclear data of Cm-244, Am-241, Pu-288, Po-210, Pm-147 Cs-137, Sr-90 and Ni-63 nuclei used in nuclear battery technology, because, these nuclei are quite important for space investigations in radioisotope thermoelectric generator (RTG) and for microelectronic technologies in betavoltaic batteries. Therefore the nuclear structure properties of nuclei such as separation energies, neutron skin thicknesses, proton, charge and neutron density distributions as a function of radius, the root mean square (rms) proton, charge and neutron radii, binding energies per particle, have been investigated by Hartree-Fock with eight different Skyrme forces. The obtained results have been compared with the experimental data in literature and relativistic mean field theory (RMFT) results.
