“…The weak γ -ray transition at 445 keV was first reported from the β-decay spectroscopy of 88 Tc following fusionevaporation reactions [69], and also seen in the γ γ coincidence projection of the 741-and 914-keV transitions in this data set. The discrepancy in the relative intensities of the 4 + 1 → 2 + 1 914-keV γ ray between this work and Ref.…”

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.

“…The calculation suggests that the two β-decaying states observed by Odahara et al [55] have spin 2 + and 6 + because a low-energy E4 transition between these two states is highly unlikely to compete with β decay. In addition, a comparison between the predicted yrast states and the experimental decay scheme strongly suggests I = 8 for the X+312 level shown on the left-hand side of Fig.…”

“…The second inset of the upper panel shows energy coincidence gates on the two transitions that are shown to not be in mutual coincidence. Two β-decaying states with half-lives of 6.4 and 5.8 s have been previously reported in this nucleus [55]. In addition, a quasirotational band was identified during an in-beam study [51] and a partial decay scheme was constructed.…”

The relativistic projectile fragmentation of a 750 MeV per nucleon beam of 107 Ag was used to populate isomeric states in neutron-deficient nuclei around A = 80-90. Reaction products were separated and unambiguously identified using the GSI FRagment Separator (FRS) and its ancillary detectors. At the final focal plane, the fragments were slowed from relativistic energies by means of an aluminium degrader and implanted in a passive stopper in the center of the high-efficiency, high-granularity Stopped Rare Isotope Spectroscopic INvestigation at GSI (RISING) germanium array. This allowed the identification of excited states in the N = Z nuclei 86 43 Tc and, for the first time, 82 41 Nb. Isomeric states have also been identified for the first time in 87,88 Tc, and a previously unreported isomer was observed in 84 Nb. Experimental results are presented along with a discussion on the structure of these nuclei based on interpretations provided by several theoretical models.

“…(6,7,8) were observed in coincidence with γ rays. The β-decay endpoint energies were measured by β-γ coincidence gated on the 741-keV γ ray and the derived Q EC values of 88 Tc were given in two different papers [70,71]. In both cases these values are significantly lower by 1.4 MeV and 2.2 MeV, respectively, than those from the systematic trends.…”

The masses of very neutron-deficient nuclides close to the astrophysical rp-and νp-process paths have been determined with the Penning trap facilities JYFLTRAP at JYFL/Jyväskylä and SHIP-TRAP at GSI/Darmstadt. Isotopes from yttrium (Z = 39) to palladium (Z = 46) have been produced in heavy-ion fusion-evaporation reactions. In total 21 nuclides were studied and almost half of the mass values were experimentally determined for the first time:88 Tc,
