“…Many spherical as well as deformed nuclei in the region 50Ͻ Z Ͻ 82 are proton emitters. Most of the measured transitions connect ground states [4][5][6][7][8][9], but in the last years also decays to excited states have been detected [10,11].…”

Proton decay from triaxially deformed nuclei is investigated. The deformation parameters corresponding to the mother nucleus are determined microscopically and the calculated decay widths are used to probe the mean-field wave function. The proton wave function in the mother nucleus is described as a resonant state in a coupled-channel formalism. The decay width, as well as the angular distribution of the decaying particle, are evaluated and their dependence upon the triaxial deformation parameters is studied in the decay of 161 Re and 185 Bi. It is found that the decay width is very sensitive to the parameters defining the triaxial deformation while the angular distribution is a universal function which does not depend upon details of the nuclear structure.

“…This effect has been observed directly in the proton [34], and the corresponding lowspin proton emitting isomers 151m Lu [35] and 150m Lu [36] the more exotic odd-odd nucleus has nearly the same proton decay energy as its odd-even less exotic partner. The information on the odd-Z isotopes gathered near 100 Sn shows a strong staggering of the proton separation energy, such that for Cs and I the odd-odd emitters have smaller decay energy than their neighbors.…”

An experiment to search for the alpha decay of 112 Cs has been performed at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory. The alpha decay of 112 Cs was not observed, thus setting the upper limit of the alpha branching ratio at 0.26%. The half-life of 112 Cs was measured as 506 ± 55 µs. In the same measurement the decay properties of its proton decay daughter 111 Xe were also reinvestigated. The newly measured alpha branching ratio for 111 Xe is 10.4 ± 1.9 %. The experimental proton separation energies Sp for odd-Z nuclei above 100 Sn were compared to shell model calculations. The calculated proton separation energies for 103 Sb and 102 Sb point to half-lives of the order of 10 ps and 1 ns, respectively.

“…proton decay. Later, a 1310(10) keV proton decay with a much shorter half-life of 16(1) μs was found in 151 Lu and assigned as proton decay from the d 3/2 isomer, the experimental spectroscopic factor for which was found to be much reduced [5].…”

The excited states of the proton emitter 151 Lu were reinvestigated in a recoil-decay tagging experiment at the Accelerator Laboratory of the University of Jyväskylä (JYFL). The level scheme built on the ground state of 151 Lu was updated with five new γ -ray transitions. Large-scale shell model calculations were carried out in the model space consisting of the neutron and proton orbitals 0g 7/2 , 1d 5/2 , 1d 3/2 , 2s 1/2 , and 0h 11/2 with the optimized monopole interaction in order to interpret the experimental level scheme of 151 Lu. It is found that the excitation energies of states above the 27/2 − and 23/2 + isomeric levels in 151 Lu can be sensitive to excitations from g 7/2 and d 5/2 to single-particle orbitals above N = Z = 64.
