Abstract：The first excited 2+ state (885 keV) of 32Mg and its corresponding deformation parameter β2 are studied with proton inelastic scattering at 190 MeV/nucleon using in-beam γ technology with a thick target. Angular distributions of the inelastic scattering cross sections are analyzed with coupled-channel calculations. The deformation parameter β2=0.41(3) obtained in this work agrees with the earlier experimental results obtained at lower beam energies. Our work demonstrates that the structure of unstable nuclei can be studied with proton inelastic scattering at high incident energies in the vicinity of 200 MeV/nucleon using thick targets.
