Nuclear Energy Levels in 44Ca using FPD6pn Interaction

Abstract

Nuclear energy levels; total angular moment, even-even parity, and even odd parities for nucleons that were present outside closed core for the isobars 44Ca nuclei, which occupied low levels fp-LS shell (1f7/2,1f5/2, 2p3/2,2p1/2), within shell model calculations had been studied. The interaction has been used to calculate the nuclear energy levels which are fpd6pnwith fp shell model space. The results are compared with each other and with available experimental data, its agreement with some results is clear. All inscriptions are given in diagrammatic notation., the wave vectors and analysis are modeled in the so-called diagrammatic notation. The potential of the oscillator is utilized to construct a single particle vector, considered as a core. The OXFORD BEUNES AIRES SHELL MODEL CODE (OXBASH) is utilized to accomplish the results for all tested nuclei, the results as illustrated in figure (1) revealing that the levels have somehow consisted especially below 4 MeV, and the order are arranged similarly to the experimental scheme. All the states inherent above 4MeV are shifted especially for the odd values of total spin (J), so the model and interaction need to be modified.
