Comparison of calculated and experimental band structure in odd-A nuclei with A=187-199

The band structure and formation mechanism of odd-A rotational bands based on intruder orbitals are studied using the particle-core coupling model of de-Shalit. Since quadrupole interaction is assumed between the particle and the core, the E2 static and transition moments of the core excited states determine the odd-A band structure. The relationship between the E2 moments of the core states and the odd-A energy spectrum is used to discuss about the core shape. Shapes considered are γ-stable, γ-vibrational, axially symmetric or spherically vibrational. This approach is found to work fairly well for the transitional nuclei with A=187-199. The γ-stable model of Davydov and Fillippov is also shown to be almost equivalent to the γ-vibrational model of Bohr and Mottelson. (Auth.)
