Gamma-ray spectroscopy of <sup>40</sup>Ca through light ion reactions

ORAL

Abstract

The study of high-spin states through in-beam γ-ray spectroscopy provides valuable information about the level structures and properties of nuclei. The 40Ca, being doubly-magic and spherical in its ground state, has multiple deformed band structures based on excited state configurations [1, 2]. In this work, light-ion scattering reactions are used to populate the level structures in 40Ca, employing particle-γ coincidence technique which is one of the powerful spectroscopic probe to study weak reaction channels. An experiment was performed at RCNP, Osaka University to study the yrast and non-yrast states in 40Ca using inelastic scattering reaction 40Ca(6Li, 6Li*) 40Ca* with incident beam energies of 130 MeV and 600 MeV. The de-excited γ-rays were detected using the CAGRA HPGe detector array in coincidence with the scattered particles detected with the Grand Raiden spectrometer. The progress of the analysis and also the future planned experiment to explore the nuclear shapes in 40Ca will be introduced.
