Systematic study of even-even 20-32Mg isotopes

Abstract EN

A systematic study for and energies for 21+and 41+ even-even 20-32 Mg by means of large-scale shell model calculations using the effective interaction USDB and USDBPN with SD and SDPN model space respectively.

The reduced transition probability B (E2 ; →) were also calculated for the chain of Mg isotopes.

Very good agreement were obtained by comparing the first 21+and 41+ levels for all isotopes with the recently available experimental data and with the previous theoretical work using 3 DAMP + GCM model, but studying the transition strengths B (E2 ; o+ gs →21+) for Mg isotopes using constant protonneutro effective charges prove the limitations of the present large-scale calculations to reproduce the experiment in detail.
