Abstract

We use the two lowest weight states to fit E2 strengths connecting the 0 harr; 2 and 2 ↔ 4 transitions in 96,98Mo. Our results confirm that the 2+ and 4+ states are maximally mixed, and that the 0+ states are weakly mixed in both nuclei. An appropriate Hamiltonian to represent the band mixing is found to be exactly solvable, and its eigenstates can be expressed as the basis vectors in the configuration mixing scheme and interacting boson model. The interacting boson model and coexistence mixing configuration under the solvable methods are suitable models for analyzing the band mixing with high accuracy.
