First strength measurements of low-energy resonances in the Sc 45 ( p , γ ) Ti 46 reaction and its astrophysical implications
The $^{45}\mathrm{Sc}(p,\ensuremath{\gamma})^{46}\mathrm{Ti}$ reaction plays an important role in both hydrostatic and explosive nucleosynthesis. During hydrostatic oxygen and silicon burning in massive stars, including dynamic processes such as convective carbon-oxygen (C-O) shell mergers, it acts as a bottleneck that regulates the reaction flow in the Sc-Ti mass region. In oxygen-neon (ONe) novae, the ejecta indicate the production of elements up to the Fe group, as observed in V1974 Cygni, and the $^{45}\mathrm{Sc}(p,\ensuremath{\gamma})^{46}\mathrm{Ti}$ reaction links nuclei above Ca to the Fe region. In core-collapse supernovae (CCSNe), it influences the production of the radioactive isotope $^{47}\mathrm{Sc}$. At present, the thermonuclear reaction rate is based on statistical model calculations. In this work, we report on measurements of the $^{45}\mathrm{Sc}(p,\ensuremath{\gamma})^{46}\mathrm{Ti}$ reaction performed using the 5 MV accelerator at the Nuclear Science Laboratory, University of Notre Dame, over a laboratory proton energy range of 526--1275 keV. We present the first direct measurements of the resonance strengths for six resonances at ${E}_{\mathrm{R}}^{\mathrm{lab}}=917.4$, 1026.0, 1031.1, 1049.7, 1059.4, and 1257.5 keV, together with integrated resonance strengths at ${E}^{\mathrm{lab}}=555$, 630, 700, 761, and 871 keV. For resonance energies below the lowest directly measured energy, available transfer-reaction data were used to estimate the resonance strengths. An updated thermonuclear reaction rate is derived, and its astrophysical implications are discussed.- 24 September 2026

Constraining the Synthesis of the Lightest p Nucleus Se 74
We provide the first experimental cross section of the ^{73}As(p,γ)^{74}Se reaction to constrain one of the main destruction mechanisms of the p nucleus ^{74}Se in explosive stellar environments. The measurement was done using a radioactive ^{73}As beam at effective center-of-mass energies of 2.9 and 2.3 MeV/nucleon. Along with the total cross-section measurement, statistical properties of the ^{74}Se compound nucleus were extracted, constraining the reaction cross section in the upper Gamow window of the γ process. The impact of the experimentally constrained reaction rate on ^{74}Se production in Type II supernovae was investigated through Monte Carlo one-zone network simulations. The results indicate that the overproduction of ^{74}Se by Type II supernova models cannot be resolved by nuclear physics alone and point toward the need for a more detailed understanding of the astrophysical conditions of relevance for the γ process.

First on-line commissioning experiments at the St. Benedict facility
Nuclear beta decays provide an excellent probe of fundamental symmetries due to their mediation by the weak interaction. In particular, precise measurements of these decays provide constraints on the unitarity of the Cabbibo-Kobayashi-Maskawa (CKM) quark-mixing matrix. While superallowed pure Fermi decays currently set the most precise limits, the alternative suite of superallowed mixed mirror decays has been ill-studied. These nuclei can provide an important consistency check of calculation and measurement methods employed for the pure Fermi decays, more critically needed now in the wake of a 2.4σ deviation from unitarity of the CKM matrix. In order to remedy the gap in data for mirror decays, the Superallowed Transition Beta-Neutrino Decay Ion Coincidence Trap (St. Benedict) facility is being commissioned at the University of Notre Dame’s Nuclear Science Laboratory (NSL). In this paper, we present first results of the commissioning of the St. Benedict facility on-line at the TwinSol radioactive beam facility. The results of initial commissioning experiments involving the St. Benedict gas catcher, RF carpet, RFQ ion guide and RFQ cooler-buncher will be presented.
