Abstract

The nuclear shell model has been employed to compute the binding energies , low-lying excitation states electric quadrupole transition rates of titanium isotopes in fp-shell region. The model space includes all configurations of nucleons in the 0f7/2 1p3/2 0f5/2 and 1p1/2 orbits, as well as the shell model describes well the energies of the intruder states. Calculations have been performed with effective interactions GXFP1 , FPD6 and KB3G in full fp space and the shell model code OXSBASH for Windows were employed . The computed binding energies, the low-lying states and electric quadrupole transition rates were in reasonably agreement with experimental data for the isotopes 42,44,46,48Ti .

Abstract

Abstract Large-scale shell model calculations for neutron-rich odd-A 63-73Ni isotopes have been performed in the lower f5/2 pg9/2-shell region. The energy levels for positive and negative parity states up to J=15/2 are calculated by using the shell model code Nushellx@msu by employing the effective interactions jun 45 and jj44b. The theoretical calculations are compared with the most recent available experimental data. Reasonable agreement is obtained between the theoretical values and the experimental data for the selected isotopes under study.
