dc.description.abstract | β
-decay rates of
121–131
Cs have been calculated in the framework of the neutron-proton interacting boson-
fermion model (IBFM-2). For odd-
A
nuclei, the decay operator can be written in a relatively simple form in terms
of the one-nucleon transfer operator. Previous studies of
β
decay in IBFM-2 were based on a transfer operator
obtained by using the number operator approximation (NOA). In this work a new form of the one-nucleon transfer
operator, derived microscopically without the NOA approximation, is used. The results from both approaches are
compared and show that the deviation from experimental data is reduced without using the NOA approximation.
Indications about the renormalization of the Fermi and Gamow-Teller matrix elements are discussed. This is
a further step toward a more complete description of low-lying states in medium and heavy nuclei which is
necessary to compute reliable matrix elements in studies of current active interest such as double-
β
