Abstract
IBM-2 calculation is presented for the low-lying states in the even-even 122-128Te core nucleus. We developed the projection by using the F-spin formalism from the operator of IBA-2 model over the operator of IBA- 1 model space. With the help of this projection IBA-2 Hamitonian parameters are obtained and we explore the energy levels and the electric quadrupole transition probabilities B (E2;Ii ® If) and g-ray E2/M1 mixing ratios for selected transitions. It was found that the calculated positive parity low spin state energy spectra of the even-even 122-128Te isotopes agree quite well with the experimental data.
