“…[35], but was later revised to 1.0(2) s [36]. Subsequent experiments confirmed the shorter half-life [27,37]. A half-life of 1.15(5) s was deduced in this work based on a fit of the βp-decay curve, again in agreement with the most recent measurements in the literature.…”

“…The total β-delayed proton branch for 93 Pd was deduced to be 7.5(5)%, similar to the upper limit of 5% reported in Ref. [27]. Taking the statistical model calculations [37] at face value, this new result is more consistent with a 7/2 + ground state for 93 Pd (b βp = 4.8%) as opposed to the previously proposed 9/2 + ground state (b βp = 1.7%).…”

β-delayed proton emission from nuclides in the neighborhood of 100 Sn was studied at the National Superconducting Cyclotron Laboratory. The nuclei were produced by fragmentation of a 120 MeV/nucleon 112 Sn primary beam on a Be target. Beam purification was provided by the A1900 Fragment Separator and the Radio Frequency Fragment Separator. The fragments of interest were identified and their decay was studied with the NSCL Beta Counting System (BCS) in conjunction with the Segmented Germanium Array (SeGA +1.9 −1.7 %, 1.3(5)%, 1.9(1)%, 7.5(5)% and 2.5(3)%, respectively. The b βp = 22(1)% for 101 Sn was deduced with higher precision than previously reported. The impact of the newly measured b βp values on the composition of the type-I X-ray burst ashes was studied.

“…The three most intense γ rays at 240, 382, and 623 keV were previously identified in a β-decay spectroscopy experiment [78], while the 894-keV γ ray was only known from the β p decay of 94 Ag [79]. Evidence for the known 853-keV γ -ray line in this data was inconclusive, and the previously identified transition at 864 keV [78] was not found-in agreement with the ENSDF evaluation. Instead, a new γ ray at 1301 keV was found.…”

A decay spectroscopy experiment on proton-rich nuclei in the vicinity of the doubly magic 100 Sn was carried out at RIKEN Nishina Center. More than 20 nuclei with 43 Z 50 and N 51, produced by fragmentation reactions were investigated via analyses of β-decay, β p-decay, and subsequent γ-ray data. Owing to higher statistics, the precision on the half-lives of many of the ground states and isomers was improved. β-decay endpoint energies of 11 states in 8 nuclei were measured for the first time, and the corresponding Q EC and excitation energies were generally consistent with various mass models. Many β-delayed proton emission branching ratios were measured either for the first time or with higher precision compared to literature values, and some of them differed by more than 2σ. Many of the large discrepancies were associated with nuclei with long-lived isomeric states, highlighting large systematic uncertainties involved in these measurements. Twenty-five new γ rays were observed, and ten new states are proposed with unambiguous excitation energies, spins, and parities. Most of the energies of the excited states were consistent within 300 keV or 20%, whichever was greater, compared to shell model predictions in the proton/neutron (p 1/2 , g 9/2) model space assuming a 76 Sr core. A signature of a new (1/2 −) isomer in 97 Cd with T 1/2 = 0.73(7) s was found, in good agreement with shell model predictions.
