Theoretical description of deformed proton emitters: Nonadiabatic coupled-channel method - art. no. 054315

The newly developed nonadiabatic method based on the coupled-channel Schrod inger equation with Gamow states is used to study the phenomenon of proton radioactivity. The new method, adopting the weak coupling regime of the par ticle-plus-rotor model, allows for the inclusion of excitations in the daug hter nucleus. This can lead to rather different predictions for lifetimes a nd branching ratios as compared to the standard adiabatic approximation cor responding to the strong coupling scheme. Calculations are performed for se veral experimentally seen, nonspherical nuclei beyond the proton dripline. By comparing theory and experiment, we are able to characterize the angular momentum content of the observed narrow resonance.
