Abstract

We calculate energy levels and B(E2) values for the $\alpha$ -like nuclei $^{104}$ Te and $^{136}$ Te. Their energy structure is described within a Multi Step Shell Model (MSM) type approach by coupling proton-proton (pp), neutron-neutron (nn) and proton-neutron(pn) phonon states over the doubly magic nuclei $^{100}$ Sn and $^{132}$ Sn, respectively. We also compute the electric transitions for A = 102 and A = 134 Sn, Sb and Te nuclei, described within the Tamm-Dankoff Approach (TDA) with multipole-multipole residual interaction. The encountered similarities concerning the B(E2) values and wavefunctions of the coupled states corresponding to $^{104}$ Te and $^{136}$ Te are analyzed.
