Calculation of Radii and Density of ^7-19B Isotopes Using Effective Skyrme Force

In this study, the proton and neutron densities, charge densities, rms nuclear charge radii, rms nuclear mass radii, rms nuclear proton, neutron radii, and neutron skin thickness are calculated by using Hartree–Fock method with an effective nucleon-nucleon Skyrme interactions with SI, SIII, SIV, T3, SKM, and SKM* parameters. These nuclear properties for the neutron-rich isotopes of B (Boron) are presented. The calculated results are compared with the experimental and theoretical results of other researchers.

Investigation of coulomb and pairing effects using new developed empirical formulas for proton-induced reaction cross sections

We have investigated Coulomb and pairing effects by using new empirical formulas including the new coefficients for (p, α) at 17.9 MeV, (p, np) at 22.3 MeV, and (p, nα) at 24.8 and 28.5 MeV energies. A new formula is obtained by adjusting Levkovskii’s original asymmetry parameter formula and also Tel et al. formula for proton-induced reactions. The new coefficients by using least-squares fitting method for the reactions are determined. In addition, the findings of the present study are compared with the available experimental data.

The effect of the initial exciton numbers on 54,56Fe(p, xp) Pre-Equilibrium Reactions

In pre-equilibrium nuclear reactions, the geometry-dependent hybrid model is applied with the use of the neutron and proton densities to investigate the effect of initial exciton numbers on the nucleon emission spectra. The initial exciton numbers calculated with the theoretical neutron and proton densities have been obtained within the Skryme-Hartree-Fock method with SKM* and SLy4 forces on target nuclei in the 54,56Fe(p, xp) reaction at 61.5-MeV incident proton energy by using a new calculationmethod of Tel et al. Also, the differences between the initial exciton numbers for protons and neutrons as a function of nuclear radius, focusing on systematic discrepancies correlated to differences in the proton and neutron densities have been investigated.

Investigation of neutron skin effect with density dependence by using a new calculation method for initial exciton numbers on pre-equilibrium reactions

In this study, we investigated the pre-equilibrium effect by using a new evaluated geometry-dependent hybrid model and a neutron skin effect with density dependence for the 204,206,207Pb(p, xn) reaction at 25.5 MeV incident proton energy. We calculated the initial exciton numbers obtained from the modified Skyrme force based on fitting the fission barriers of heavy deformed nuclei (SKM*) and SLy4 for proton induced reaction on target nuclei 204,206,207Pb. We calculated, by using a new calculation method, the initial neutron and proton exciton numbers for 204,206,207Pb from the neutron and proton density and we investigated the shell effect by using an effective nucleon–nucleon interaction with Skyrme force. We also compared the geometry-dependent hybrid model (GDH), newly evaluated with the initial exciton number calculations of the neutron emission spectra of the 204,206,207Pb(p, xn) reaction, with the values reported in the literature at 25.5 MeV incident proton energy. The obtained results were investigated and compared with the pre-equilibrium calculations and experimental results.
