Description
The proton-neutron interaction boson model (IBM-2) describes energies, B(E2) and B(M1) values of nuclei. In order to reduce the great number of free IBM-2 parameters two special IBM-2 hamiltonians are proposed which allow a decoupling of the energy and B(E2) fit from the determination of the B(M1) values and the energy of the lowest mixed symmetry 1+ state. This property allows a simple fit procedure of the IBM-2 parameters in both cases. (orig.)
