Description
Due to scarcity of experimental data the variation of 2^+_1 energies for heavier Sn isotopes (A \geq 136) is still a topic for serious theoretical endeavours by different groups. Large basis untruncated shell model calculations have been done in the p(gdsh) + n(hfpi) valence space above the 132Sn core using both realistic and empirical (1+2) - body Hamiltonians. A new shell closure for neutron rich Sn isotopes has been predicted from these calculations using empirical SMPN interaction that works successfully in this neutron rich domain. Calculations with realistic two-body interaction CWG also predict this shell closure provided a three-body force contribution is included in it. The calculated E(2^+_1) values for 134-140Sn fits nicely in the systematics and shows dramatic resemblance with the trends shown by even-even 18-22O and 42-48Ca.
