Boson-conserving one-nucleon transfer operator in the interacting boson model
(American Physical Society, 2002-03-01)
The boson-conserving one-nucleon transfer operator in the interacting boson model (IBM) is reanalyzed. Extra terms are added to the usual form used for that operator. These new terms change generalized seniority by ...

One nucleon transfer operator and nuclear supersymmetry
(American Physical Society, 2005-01-01)
The appropriate use of the interacting boson-fermion model one nucleon transfer operator in connection with nuclear supersymmetries is discussed. We emphasize that care must be taken in using the same coupling ...

β-decay rates of 121–131Cs in the microscopic interacting boson-fermion model
(American Physical Society, 2016)
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 ...

Odd-even 147–153Pm isotopes within the neutron-proton interacting boson-fermion model
(American Physical Society, 2011)
Low-lying energy states of the 147 -153Pm isotopic chain are studied within the framework of the neutron-proton interacting boson-fermion model (IBFM-2). The spectra of these isotopes show a transition from a particle ...

The one nucleon transfer operator in the microscopic IBM without NOA
(Elsevier, 2014)
The mapping of the single fermion creation operator (ci†) onto the Interacting Boson-Fermion space (IBFM) is revisited within the Generalized Seniority scheme. In the original work the Number Operator Approximation (NOA) ...
