Decay Rate of Triaxially-Deformed Proton Emitters
Cary N. Davids, Henning Esbensen
Abstract
The decay rate of a triaxially-deformed proton emitter is calculated in a particle-rotor model, which is based on a deformed Woods-Saxon potential and includes a deformed spin-orbit interaction. The wave function of the I=7/2- ground state of the deformed proton emitter 141Ho is obtained in the adiabatic limit, and a Green's function technique is used to calculate the decay rate and branching ratio to the first excited 2+ state of the daughter nucleus. Only for values of the triaxial angle γ <5 is good agreement obtained for both the total decay rate and the 2+ branching ratio.
