Effects of triaxial deformation and pairing correlation on the proton emitter (145)Tm

The ground-state properties of the recent reported proton emitter (145)Tm have been studied within the axially or triaxially deformed relativistic mean field (RMF) approaches, in which the pairing correlation is taken into account by the BCS-method with a constant pairing gap. It is found that triaxiality and pairing correlations play important roles in reproducing the experimental one proton separation energy. The single-particle level, the proton emission orbit, the deformation parameters beta=0.22 and gamma=28.98 degrees and the corresponding spectroscopic factor for (145)Tm in the triaxial RMF calculation are given as well.Physics, NuclearSCI(E)0ARTICLE2null7
