Odd-odd interacting-boson-approximation calculations: Experimental agreement for doubly decoupled and highly distorted bands inRe176–180

We present results of interacting-boson-fermion-fermion approximation (IBFFA) calculations for deformed odd-odd $^{176}\mathrm{Re}$ and $^{178}\mathrm{Re}$. Such calculations yield accurate structural information for many different rotational band types, including highly distorted and doubly decoupled bands. Thus, they can help in interpreting experimental data, predicting spin-parity assignments that agree with those obtained by other methods, and giving rather good predictions for interband transition energies. We also compare our previously published IBFFA predictions for $^{180}\mathrm{Re}$ with new experimental data.
