Paper Abstract

We present results of theoretical nuclear structure model calculations for the gamma-ray laser candidate nucleus 186Re proposed by Collins. Our calculations of this odd-odd transitional nucleus are based on an axially-asymmetric (particle plus triaxial rotor) model for constructing the orbitals of the odd nucleons that couple under the influence of the residual neutron-proton interaction. We include pairing correlations in the determina-tion of these orbitals by using the BCS ap-proximation with newly determined pairing strengths. The matrix elements of the resid-ual neutron-proton interaction are obtained using phenomenological spin-dependent 8 function potentials of both surface and volume forms. We examine the sensitivity of the calculated low-excitation level structure of 186Re to the strength of these potentials. Calculated energy levels of 186Re will be presented and compared with experiment. The impact of our results on the proposed use of 186Re as a gamma-ray laser will be discussed. In addition, based upon these and other model calculations to be described, we assess the level of effort necessary in a full-scale the-oretical search for a viable candidate nucleus for a gamma-ray laser.
