Description
Excited states in the 42Si nucleus have been studied via in-beam gamma-ray spectroscopy following two-proton removal reaction to investigate the structure of 42Si, such as the nuclear shape or information on the shell evolution.
The experiment was performed at RI Beam Factory operated by RIKEN Nishina Center and CNS, University of Tokyo. The secondary beam of 44S and outgoing particles were identified by the BigRIPS separator and the ZeroDegree spectrometer, respectively. De-excitation gamma rays were detected by the DALI2 gamma-ray detection array in coincidence with 42Si particles. We observed the prominent peak corresponding to the first 2+ state in the gamma-ray spectrum with high statistics and other gamma lines. We will report the experimental results and the candidate of the 4+ state.
