The boson expansion theory is applied to even Se and Kr isotopes with neutron number N=38-48. Energy spectra, B(E2) values and quadrupole moments are calculated and fairly good agreement with experimental data is obtained. The coupling of collective

Mathematical aspects of the commutator method, which is one of the fashionable boson expansions methods, are investigated in great detail. We intend to obtain all the possible solutions of the equations for the expansion coefficients. We show first t

A new boson expansion theory based on the random phase approximation is presented. The boson expansions are derived here directly in the random phase approximation representation with the help of a technique that combines the use of the Usui operator

A boson-expansion formalism is based on the random-phase approximation set forth in a previous publication is extended and brought into a form amenable to practical calculations. The boson forms of the collective Hamiltonian electric quadrupole and m

Formal aspects of boson expansions in the Tamm-Dancoff representation are investigated in detail. This is carried out in the framework of the extended commutator method by solving in complete generality the coefficient equations, searching for Hermit
