Shell structure near $^{42}$Si: one proton knockout from $^{44}$S

ORAL

Abstract

The $d_{5/2}$ proton strength in $^{43}$P was studied via the one-proton knockout reaction $^9$Be($^{44}$S,$^{43}$P)X. Gamma rays were measured in coincidence with the knockout products. We extracted spectroscopic factors of states populated in the reaction from measured parallel momentum distributions. An expanded level scheme will be presented and the size of the $Z=14$ proton subshell closure will be discussed.
