Triaxially deformed proton emitters.

The role of triaxial deformation in proton emitting nuclei is studied with the nonadiabatic quasiparticle method. Exact calculations are done using this formalism which takes fully into account the pairing residual interaction and the coupling to the daughter nucleus states. Results from our calculations for the proton emitters ¹⁶¹Re and ¹⁸⁵Bi are presented and the influence of triaxial deformation on the decay and structural properties of these nuclei are discussed. We predict that the half-lives for proton emission from these nuclei have a weak dependence on triaxial deformation, especially in the non-adiabatic case. [ABSTRACT FROM AUTHOR]
