It is shown that the multiparticle theory of proton radioactivity (MTPR), based on the integral formulas for proton widths, has sufficiently high accuracy and totality for description of deep subbarrier proton decay of nuclei. The theoretical scheme of calculation for proton widths of odd-odd deformed nuclei is created. The connection of fine proton spectrum structure with types of proton orbit in 141Ho141Hois analyzed. It is shown that nuclear deformation parameters, found for investigation of proton decay of deformed odd-even and odd-odd nuclei and predicted by some systematics are the same. ©2000 American Institute of Physics.
