Particle-vibration coupling in proton decay of near-spherical nuclei

A particle-vibration coupling model is applied to explain the spectroscopic factors and decay rates of odd-A and odd-odd near-spherical proton emitters, as well as the branching ratio for the recently observed fine structure in the decay of {sup 145}Tm. In addition, a deformed solution for {sup 145}...

Description
Summary:A particle-vibration coupling model is applied to explain the spectroscopic factors and decay rates of odd-A and odd-odd near-spherical proton emitters, as well as the branching ratio for the recently observed fine structure in the decay of {sup 145}Tm. In addition, a deformed solution for {sup 145}Tm with K=5/2{sup -} is presented. Using particle-vibration coupling, good agreement is achieved with observed spectroscopic factors for the near-spherical emitters, including d{sub 3/2} cases. For the odd-odd emitters, the unpaired neutron is treated as a spectator. The single-particle potential used in this work has the same parameters as that used to successfully describe the decay rates of the deformed proton emitters {sup 131}Eu and {sup 141}Ho.
