Narrow Results

In this paper, we intend to extend the nuclear data of ${}^{244}\mathrm{\text{Cm}}$, ${}^{241}\mathrm{\text{Am}}$, ${}^{238}\mathrm{\text{Pu}}$, ${}^{210}\mathrm{\text{Po}}$, ${}^{147}\mathrm{\text{Pm}}$, ${}^{137}\mathrm{\text{Cs}}$, ${}^{90}\mathrm{\text{Sr}}$ and ${}^{63}\mathrm{\text{Ni}}$ 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.

This work aimed to investigate the production of ${}^{151}$Sm and ${}^{152,154,155}$Eu on natural Nd and Sm targets via particle accelerator because these radionuclides have the potential for use in nuclear battery technology such as betavoltaic batteries and radioisotope thermoelectric generators. Therefore, this work estimated cross-section curves for proton, deuteron, triton, helium-3, and alpha particles induced reactions in the energy range $E_{\mathrm{\text{particle}}}=100\to 1\mathrm{\text{MeV}}$. The activities and products of yield were simulated for all reaction processes under selected conditions, the particle beam current of 1 mA and the irradiation time of 24 h. Moreover, to understand the formations of ${}^{151}\mathrm{\text{Sm}}$ and ${}^{152,154,155}$Eu in the reaction processes, the appropriate energy region of the reactions by calculating the integral yield curves were determined. Based on the obtained results, determination of suitable targets, energy regions, and reaction processes were discussed by this work.

Aims of this work are: (i) Investigation of the production of some radioisotopes that could be used in nuclear battery technology with neutron-induced reaction processes, (ii) Estimation of the cross-section curves of $(n,\gamma )$ reactions for astrophysical processes in the energy region between 1eV and 1MeV, (iii) Determination of suitable level density models for the $(n,\gamma )$ reaction processes. Additionally, the obtained results were compared with the experimental data and recommended data. Based on the calculated results, to eliminate lack of nuclear data in the literature, we recommend new experiments for some reaction processes to be performed by the experimenters. Moreover, for the $(n,\gamma )$ reaction processes, suitable level density models were proposed.
