Abstract

In many nuclei the coexistence of two quite different structures in the same energy region is manifest in the experimental data. Generally there is configuration mixing between these structures. We present a new, general technique for providing a quantitative description of configuration mixing in nuclei. The technique uses the interacting boson model for protons and neutrons to make separate descriptions of the different configurations, which are then mixed using an appropriate mixing hamiltonian. Examples are given using the mercury and molybdenum isotopes.
