Complimentary Approaches to the Study of T=2 30Al

ORAL

Abstract

Excited states in $^{30}$Al were populated through the $^{14}$C($^{18}$O, pn$\gamma$)$^{30}$Al fusion evaporation reaction at an energy of 22 MeV at Florida State University. In addtion, $^{30}$Al was studied by the $\beta$-decay of $^{30}$Mg produced by the intermediate energy projectile fragmentation of $^{48}$Ca beam at 140 MeV/nucleon on $^{9}$Be at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University. Through the $\beta$-decay results, the half-life of the parent nucleus, $^{30}$Mg, was found to be 315 $\pm$ 6 ms which is in good agreement with previous results. Also, the previously known low-lying $\gamma$ transitions were observed. In addtion, two new lines were observed leading to a new 1$^{+}$ state. The in-beam analysis yielded many new states that appear to have relatively high-spin ($\ge$ 4$^{+}$). Results, thus far, from both experiments are in good agreement with each other, shell model predictions, and previous work. This work was supported in part by the National Science Foundation.
