Abstract

The coupled-channel Schrödinger 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 $^{131} Eu$ and $^{141} Ho$ . Experimental lifetimes and proton-decay branching ratios are reproduced. Variations with the standard adiabatic theory are discussed.
