Detailed study of $^{21}$Mg excited states in one neutron knockout.

ORAL

Abstract

The identification of excited state properties of $^{21}$Mg has so far been directed by comparison to the mirror nucleus $^{21}$F. To obtain independent information on excited states in $^{21}$Mg this nucleus is investigated in the single neutron knockout reaction: $^9$Be($^{22}$Mg,$^{21}$Mg)X. Following the knockout, the $\gamma$-decays are studied using in-beam $\gamma$-ray spectroscopy. From the $\gamma$-ray data, the properties of bound states in $^{21}$Mg are identified. Similarly, spectroscopic factors for the $^{22}$Mg ground state are determined through the individual level feedings.
