Abstract
Proton decay from odd-odd deformed nuclei is a long-standing unsolved problem. We present for the first time an exact solution using single particle Nilsson resonances. The lifetime is found to depend strongly on the single particle level occupied by the unpaired neutron, allowing a clear assignment of its Nilsson level. The emitters , , , and are considered. The agreement with the experimental data is very good with deformations for and for the ground and isomeric states of . In the case of , two ranges of deformation and according to the neutron single particle level can describe the experimental half-life.
