A variational approach to calculating IBM1 parameters and properties of even tellurium isotopes

Resumo

A variational approach to determining Bogolyubov’s parameters, the amplitudes of a collective quadrupole phonon that is an image of IBM1 d-boson, and the boson composition of wave functions is applied to even Te isotopes with А = 116–128. A satisfactory description of the energies and В(Е2) probabilities of low-lying collective states is obtained. The calculation of quadrupole moments for the first 2₁⁺-states requires some alterations to be made to the single-particle spin–orbital potential, compared to the one that was fixed for nuclei adjacent to double-magic Sn isotopes with Z = 50 and A = 50, 82.
