In the region around 132Sn, the structure of even-even nuclei demonstrates diverse phenomenon including the transition between some typical quadrupole collective states. The doubly magic isotopic chain of Sn-isotopes seems to be the most interesting mass-region to be studied. Several theoretical and experimental studies have been focused in this mass region, recently [1]. The low-lying spectroscopy of these nuclei is one of the most powerful sources of information about nuclear shapes and shape transitions. Experimental/adopted B(E2↑) values for this mass-region are depicted in Fig. 1.
