Intruder Structure in N=21, $^{38}$Cl Isotope

Excited states of the $^{38}$Cl isotope were populated by the $^{26}$Mg($^{18}$O,$\alpha pn\gamma$)$^{38}$Cl fusion evaporation reaction at $E_{lab}=50$ MeV. The $^{18}$O beam accelerated by a Tandem accelerator at John. D. Fox laboratory, Florida State University, was incident on an enriched $^{26}$Mg target. Four clover detectors and one single crystal HPGe detector were used in order to detect the de-exciting $\gamma$ rays, where a $E-\Delta E$ detector was used to select the charged particles emitted from the compound nucleus $^{44}$Ca. The $\gamma-\gamma$ coincidence method, along with the coincidence with charged particles was employed in order to assign new $\gamma$ rays in $^{38}$Cl and to verify the existing ones. The experimental observations will be compared to the shell model calculations with a new interaction currently being developed by the Florida State University Nuclear Physics group.
