Background: The structure of the Hoyle state, a highly $\alpha$-clustered state at 7.65 MeV in $^{12}\mathrm{C}$, has long been subject debate. Understanding if system comprises three weakly-interacting $\alpha$-particles 0s orbital, known as an $\alpha$-condensate is possible by studying decay branches state. Purpose: direct into $\alpha$-particles, rather than through $^{8}\mathrm{Be}$ ground can be identified energy partition 3 arising from decay. This paper provides details on break-up...
Integral benchmarks for criticality safety and nuclear data validation require expensive uncertainty quantification studies. In general, techniques ignore correlations between experiments shared components. Experiments, such as the Thermal/Epithermal eXperiments (TEX) campaigns, consist of many components, Jemima highly enriched uranium (HEU) fuel plates, which create a strong correlation in their uncertainties. While these are known to exist, they often not estimated because complexity...
Background: The Efimov effect is a universal phenomenon in physics whereby three-body systems are stabilized via the interaction of an unbound two-body subsystems. A hypothetical state $^{12}\mathrm{C}$ at 7.458-MeV excitation energy, comprising loose structure three $\ensuremath{\alpha}$ particles mutual resonance, has been suggested literature to correspond nuclear physics. existence such not demonstrated experimentally.Purpose: Using combination $\ensuremath{\gamma}$ spectroscopy,...
Direct measurements of the total fusion cross section for B8+40Ar were achieved with active target technique. The excitation function was extracted at energies near Coulomb barrier. is well described by a coupled reaction channels calculation. data compared previous B8 experiments on Si28 and Ni58 targets. No evidence striking enhancement barrier, that previously reported B8+58Ni system, observed in these direct measurements. present are systematically consistent results B8+28Si higher other...
Abstract In the past several years, there has been a large interest of Time Projection Chambers (TPCs) for use in experimental nuclear physics. This continued tandem with requirement high efficiency detectors low intensity radioactive ion beams. TexAT is Active Target TPC (AT-TPC) built at Texas A&M University utilizing MICRO MEsh GASeous (MicroMegas) pads and GET electronics developed specifically TPCs. design combines good pixelation surrounding shell Si/CsI telescopes to make an...
In this paper, we study \ensuremath{\alpha} clustering in $^{18}\mathrm{Ne}$ and compare it with what is known about the mirror nucleus $^{18}\mathrm{O}$. The excitation function for $^{14}\mathrm{O}+\ensuremath{\alpha}$ resonant elastic scattering was measured inverse kinematics using Texas active target detector system (TexAT). data cover excitation-energy range from 8 to 17 MeV. analysis performed a multichannel $R$-matrix approach. detailed spectroscopic information obtained analysis:...
Background: Spectroscopy of the exotic, neutron unbound beryllium isotope $^{13}\mathrm{Be}$ is still a puzzle despite significant experimental efforts.Purpose: We aim to observe $T=5/2$ states in $^{13}\mathrm{B}$, establish spin-parities and spectroscopic factors, use isospin symmetry inform spectroscopy $^{13}\mathrm{Be}$.Methods: Excitation functions for resonance elastic scattering $^{12}\mathrm{Be}$ on protons were measured center-of-mass energy range from 1 5 MeV.Results: Two...
Background: $^{32}\mathrm{Cl}$ is a neutron-deficient isotope with $\ensuremath{\beta}$-decay half-life of 298 ms and spin parity ${J}^{\ensuremath{\pi}}={1}^{+}$. Previous measurements $^{32}\mathrm{Cl} \ensuremath{\beta}$-delayed $\ensuremath{\gamma}$ rays have yielded scheme twelve transitions, contributing to studies nuclear structure fundamental symmetries. Those experiments been limited the observation $^{32}\mathrm{S}$ states ${J}^{\ensuremath{\pi}}={0}^{+},{1}^{+},{2}^{+}$.Purpose:...
