The ^{30}P(p,γ)^{31}S reaction plays an important role in understanding the nucleosynthesis of A≥30 nuclides oxygen-neon novae. Gaseous Detector with Germanium Tagging was used to measure ^{31}Cl β-delayed proton decay through key J^{π}=3/2^{+}, 260-keV resonance. intensity I_{βp}^{260}=8.3_{-0.9}^{+1.2}×10^{-6} represents weakest β-delayed, charged-particle emission ever measured below 400 keV, resulting a branching ratio Γ_{p}/Γ=2.5_{-0.3}^{+0.4}×10^{-4}. By combining this measurement...
The radionuclide $^{22}\mathrm{Na}$ is a target of $\ensuremath{\gamma}$-ray astronomy searches, predicted to be produced during thermonuclear runaways driving classical novae. $^{22}\mathrm{Na}(p,\ensuremath{\gamma})\phantom{\rule{0.16em}{0ex}}^{23}\mathrm{Mg}$ reaction the main destruction channel nova, hence, its rate needed accurately predict yield. However, experimental determinations resonance strengths have led inconsistent results. In this Rapid Communication, we report measurement...
$\beta$-decay spectroscopy provides valuable information on exotic nuclei and a stringent test for nuclear theories beyond the stability line. To search new $\beta$-delayed protons $\gamma$ rays of $^{25}$Si to investigate properties $^{25}$Al excited states. $\beta$ decays were measured by using Gaseous Detector with Germanium Tagging system at National Superconducting Cyclotron Laboratory. The emitted in decay detected simultaneously. A Monte Carlo method was used model Doppler broadening...
The timely detection of special nuclear material (SNM) transfers between facilities is an important monitoring objective in nonproliferation. Persistent enabled by successful and characterization radiological movements could greatly enhance the nonproliferation mission a range applications. Supervised machine learning can be used to signal detections when present if model trained on sufficient volumes labeled measurements. However, data needed train robust models costly label since radiation...
Data analysis techniques can be powerful tools for rapidly analyzing data and extracting information that used in a latent space categorizing observations between classes of data. Machine learning models exploit learned relationships address variety nuclear nonproliferation challenges like the detection tracking shielded radiological material transfers. The high resource cost manually labeling radiation spectra is hindrance to rapid collected from persistent monitoring adoption supervised...
