Abstract
The higher-spin structure of Cl38 (N=21) was investigated following the Mg26(C14, pn) reaction at 30 and 37 MeV beam energies. The outgoing protons were detected in an E-ΔE Si telescope placed at 0 close to the target with a Ta beam stopper between the target and telescope. Multiple γ rays were detected in time coincidence with the protons using an enhanced version of the FSU γ-detection array. The level scheme was extended up to 8420 keV with a likely spin of 10�. A new multishell interaction was developed guided by the experimental information. This FSU interaction was built by fitting to the energies of 270 experimental states from C13 to Ti51. Calculations using the FSU interaction reproduce observed properties of Cl38 rather well, including the spectroscopic factors. The interaction has been successfully used to interpret the 1p1h and 2p2h configurations in some nearby nuclei as well.
