Structure of $^{41}$K and $^{41}Ca

The nuclei of interest, $^{41}$K and $^{41}$Ca, straddle the N/Z = 20 shell gap and subsequently give insight into the evolving shell structure surrounding this region. The addition to the high-spin structure of these nuclei results from the augmented FSU high purity germanium detector array. The nuclei were produced by bombarding a $^{26}$Mg target with a 50 MeV $^{18}$O beam from the John D. Fox Superconducting Linear Accelerator Laboratory at Florida State University. Several new levels and gamma decays have been observed. Additionally, spins and parities have been measured. The structure of these nuclei will be compared with predictions of the spsdpf cross-shell FSU shell model interaction.
