“…The decimal logarithm deviations between the experimental data and the calculated results using these models and formulas are almost an order of magnitude. In fact, the probability of one proton emission depends on the deformation of the system and the effects arising from the deformed shape, especially for the triaxial (see, for example 141 Ho [77]) and oblate deformed (such as the Bi isotopes, see [78][79][80]) one proton emitters. Thus, the deformation effect can not be ignored for further study on one proton radioactivity half-lives of deformed proton emitters.…”

In present work, a phenomenological one-parameter model (OPM) based on the Wentzel-Kramers-Brillouin (WKB) theory is applied to study the favored one proton radioactivity (the orbital angular momentum l taken away by the emitted one proton equals to zero) half-lives. The calculated results can reproduce the experimental data well within a factor of ∼ 3. In addition, we extend the OPM to predict the half-lives of possible favored one proton radioactivity nuclei whose decay is energetically allowed or observed but not quantified in NUBASE2020. For comparison, a universal decay law of one proton radioactivity (UDLP) is also used. It is obviously found that our predicted results are close to the ones using UDLP. The predictions are helpful for searching for the new nuclides with favored one proton radioactivity.

“…Ground-state proton emission [6][7][8][9][10][11] was found in the early 1980s via the discovery of 151 Lu [12], shortly followed by the identification of 147 Tm [13] (T1 /2 = 0.58(3) s [14]). To date, approximately 50 [10] cases of proton emission are known between 108 I [5] and 185 Bi [15]; the only odd-Z element in between without observed proton emission is promethium. The proton-emission rate is only sensitive to the energy released in the decay Q p , the angular momentum l p carried away by the emitted proton, and the shape of the decaying nucleus.…”

Two triaxial states of the proton-decaying nucleus 147 Tm were studied via a comparison of experimental data to results obtained through nonadiabatic quasiparticle calculations. The experimental data were collected in a recoil-decay tagging study using the vacuum-mode recoil separator MARA coupled with the JUROGAM3 γ -ray spectrometer. The previously proposed level scheme above the triaxial 11 /2 − (π h11 /2 ) ground state was confirmed, and the level structure was expanded to cover the states above the weakly populated proton-emitting 5 /2 + (π d5 /2 ) isomeric state. It was found that the isomeric state is also triaxial, and possibly more deformed than the ground state.
