Analysis of $^{36,38,40}$Si by Gamma Ray Spectroscopy of Fragmentation Reactions

POSTER

Abstract

We report the results of an experiment performed at the National Superconducting Cyclotron Laboratory (NSCL) where a $\approx$ 100 MeV/nucleon exotic cocktail beam with primary components $^{44}$S and $^{45}$Cl was fragmented in a $^{9}$Be reaction target to produce $^{36,38,40}$Si. The Gamma rays emitted by the reaction products were detected with the Segmented Germanium Array (SeGA), and the exotic nuclei produced were identified by the S800 magnetic spectrograph. The gamma-ray energy spectra observed are consistent with prior measurement [1]. In addition, we observed three additional gamma rays in $^{40}$Si. [1] C.M.Campbell et al., Phys.Lett.
