$^{10}B(d,p)^{11}B$ and $^{25}Mg(d,p)^{26}Mg$ measurements using the Super-Enge Split-Pole Spectrograph

Two experiments were preformed using the Super-Enge Split-Pole Spectrograph at Florida State University’s John D. Fox Accelerator Laboratory to measure high-resolution spectra of states in $^{26}Mg$ and $^{11}B$ through the use of (d,p) single-particle transfer reactions. Spin assignment confirmation of five states above the proton threshold of $^{26}Si$ are necessary for assessing the astrophysical impact of the $^{25}Al(p,\gamma)$ reaction rate on the $^{26}Al$ cosmic abundance. We investigate $^{25}Mg(d,p)^{26}Mg$ as a mirror to $^{26}Al$ to assign spin to the mirrors to the states of interest. A previous study observed beta-delayed proton emission in the neutron-rich nucleus $^{11}Be$ with an unexpectedly high decay mode strength that can only be understood if the decay proceeds through a new single-particle resonance in $^{11}B$ strongly fed by beta-decay. A recent pre-print corroborates the study, providing the expected excitation energy. While the resonance in $^{11}B$ was not found, spin assignments of $^{11}B$ states were assigned, one of which was previously unassigned.
