Abstract
The {ital F}-spin mixing and {ital M}1 properties of the low-lying bands in the neutron-proton interacting boson model (IBM-2) are studied. Application of the intrinsic state formalism in the leading order in 1/{ital N} and of the perturbative approach makes it possible to obtain analytical expressions in which a dependence on {ital F}-spin breaking terms is clearly exhibited. A simple explanation of many features observed in numerical studies is given. Comparison between the IBM-2 results and the treatment of {ital M}1 properties with the extended {ital M}1 operator in the IBM-1 approach is discussed.
