Introduction Direct reactions are crucial tools for accessing properties of the atomic nucleus. Fundamental and exotic phenomena such as collective modes, pairing, weakbinding effects evolution single-particles energies can be investigated in peripheral collisions between a heavy nucleus light target. The necessity using inverse kinematics to reveal how these structural change with isospin imbalance renders direct challenging technique when missing mass method. Methods In this scenario,...
We performed a measurement of the $^{51}\mathrm{V}(d,p)^{52}\mathrm{V}$ reaction at 16 MeV using Florida State University Super-Enge Split-Pole Spectrograph (SE-SPS) to search for single-neutron transfer strength ${g}_{9/2}$ intruder orbit. Measurements $\ensuremath{\nu}{g}_{9/2}$ with ($d,p$) reactions in $N=29$ isotones $^{49}\mathrm{Ca}, ^{51}\mathrm{Ti}, ^{53}\mathrm{Cr}$, and $^{55}\mathrm{Fe}$ have concluded that much expected is ``missing''; is, summed smaller than sum rule. In...
Single-step Coulomb excitation of 46,48,49,50Ti is presented. A complete set E2 matrix elements for the quintuplet states in 49Ti, centred on 2+ core excitation, was measured first time. total nine are reported, four which were previously unknown. 2249Ti27 shows a 20% quenching electric quadrupole transition strength as compared to its semi-magic 2250Ti28 neighbour. This quenching, while empirically unprecedented, can be explained with remarkably simple two-state mixing model, also...
A measurement of the $^{54}\mathrm{Fe}(d,p)^{55}\mathrm{Fe}$ reaction at 16 MeV was performed using Florida State University Super-Enge Split-Pole Spectrograph to determine single-neutron energies for $2{p}_{3/2}, 2{p}_{1/2}, 1{f}_{5/2}, 1{g}_{9/2}$, and $2{d}_{5/2}$ orbits. Two states were observed that had not been in previous ($d,p$) measurements. In addition, we made angular momentum transfer, $L$, assignments four changed $L$ from measurements nine more states. The spin-orbit splitting...
We performed a measurement of the $^{52}$Cr$(d,p)^{53}$Cr reaction at 16 MeV using Florida State University Super-Enge Split-Pole Spectrograph (SE-SPS) and observed 26 states. While all states here had been seen in previous $(d,p)$ experiments, we changed five $L$ assignments from those reported previously determined values for nine that not such made previously. The $g_{9/2}$ neutron strength $^{53}$Cr present work $N=29$ isotones $^{49}$Ca, $^{51}$Ti, $^{55}$Fe via reactions is much...
The $^{25}\mathrm{Al}(p,\ensuremath{\gamma})^{26}\mathrm{Si}$ reaction plays a key role in accurately modeling and understanding the nucleosynthesis of long-lived radioisotope $^{26}\mathrm{Al}$ observed throughout galaxy by $\ensuremath{\gamma}$-ray telescopes via detection its 1.809 MeV line. is responsible for redirecting flux nuclear material away from ground state ($^{26}\mathrm{Al}^{g}$) favor short-lived isomer ($^{26}\mathrm{Al}^{m}$) which bypasses emission $\ensuremath{\gamma}$...
A measurement of the $^{50}$Ti($d$,$p$)$^{51}$Ti reaction at 16 MeV was performed using a Super Enge Split Pole Spectrograph to measure magnitude $N=32$ subshell gap in Ti. Seven states were observed that had not been previous ($d$,$p$) measurements, and \textit{L} transfer values for six previously measured either changed or first time. The results used determine single neutron energies $p_{3/2}$, $p_{1/2}$ $f_{5/2}$ orbitals. resulting $^{51}$Ti confirm existence These those from...
Single-step Coulomb excitation of $^{46,48,49,50}$Ti is presented. A complete set $E2$ matrix elements for the quintuplet states in $^{49}$Ti, centered on $2^+$ core excitation, was measured first time. total nine are reported, four which were previously unknown. $^{49}_{22}$Ti$_{27}$ shows a $20\%$ quenching electric quadrupole transition strength as compared to its semi-magic $^{50}_{22}$Ti$_{28}$ neighbour. This quenching, while empirically unprecedented, can be explained with remarkably...
Purpose: Single-neutron adding data was collected in order to determine the distribution of single-neutron strength $0f_{7/2}$, $1p_{3/2}$, $1p_{1/2}$ and $0f_{5/2}$ orbitals outside $Z=16, N=18$, $^{34}$S. Methods: The $^{34}$S($d$,$p$)$^{35}$S reaction has been measured at 8 MeV/u investigate cross sections excited states $^{35}$S. Outgoing proton yields momenta were analyzed by Super-Enge Split-Pole Spectrograph conjunction with CeBrA demonstrator located John D. Fox Laboratory Florida...

We describe a methodology for constructing tabular potentials of supertoroids with short-range interactions, which requires the calculation volume overlap these shapes many relative positions and orientations. Recent advances in synthesis anisotropic colloids have made experimental realizations such particles feasible increased practical impact fundamental simulation studies families shapes. This extends our recent work on superquadric to now include family ring-like hole middle. Along...
The $\mathrm{^{25}Al(p,\gamma)^{26}Si}$ reaction is part of a network with impact on the observed galactic $^{26}$Al abundance. A new determination proton strength lowest $\ell=0$ proton-resonance in $^{26}$Si required to more precisely calculate thermal rate. To this end, $\mathrm{^{25}Al(d,n)^{26}Si}$ proton-transfer measured inverse kinematics using an in-flight radioactive beam at RESOLUT facility. Excitation energies resonances are and cross sections determined for resonance associated...
