Elastic and inelastic scattering of protons on 38S in inverse kinematics

Abstract

Elastic and inelastic scattering of protons on unstable 38S nuclei has been measured in inverse kinematics by using a 38S secondary beam at 39 MeV/nucleon. The excitation energy spectrum is measured up to 5 MeV. The first 2 + state is seen at 1.2 MeV excitation energy, and strength at around 3–5 MeV is also observed. Angular distributions for inelastic and elastic scattering are shown and compared to optical potential and folding model calculations. The preliminary β 2 value extracted for the first 2 + state is 0.38±0.05.
