Title: Fine Structure in the Decay of Deformed Proton Emitters: Nonadiabatic Approach

Abstract

The coupled-channel Schroedinger equation with outgoing wave boundary conditions is employed to study the fine structure seen in the proton decay of deformed even-N , odd-Z rare earth nuclei {sup 131}Eu and {sup 141}Ho . Experimental lifetimes and proton-decay branching ratios are reproduced. Variations with the standard adiabatic theory are discussed. (c) 2000 The American Physical Society.
