Study of the Structure of Exotic 52,54,56,58Ca Isotopes Using OXBASH Code

Abstract

This study dedicates to provide an information of shell model calculations,limited to fp-shell with an accuracy and applicability. The estimations depend on theevaluation of Hamiltoian’s eigenvalues, that’s compatible with positive parity ofenergy levels up to (10MeV) for most isotopes of Ca, and the Hamiltonianeigenvectors transition strength probability and inelastic electron-nucleus scattering.The Hamiltonian is effective in the regions where we have experimented. Theknown experimental data of the same were confirmed and proposed a new nuclearlevel for others.The calculations are done with the help of OXBASH code. The results showgood agreement with experimental energy states for 52,54Ca isotopes while a newresult are gotten for 56,58Ca isotopes as it is a modern nucleus investigation. For 58Ca, the results are given a smallest 2+ excitation energy with strong B(E2) confirmedby large-“scale shell model in fp-shell space that cannot describe the small energyE(2+) besides that, the reduce transition probability B(E2) in each interaction isdifferent.
