γ spectroscopy around doubly magic 48Ca by heavy-ion transfer reactions

γ spectroscopy of neutron-rich nuclei around 48Ca is performed by the heavy-ion transfer reaction 48Ca on 64Ni at 282 MeV, with the PRISMA-CLARA setup at Legnaro Laboratory. Angular distributions, polarizations and lifetimes analysis probe spin and parities of several excited states, shading lights on their configuration. In the one neutron transfer channels, 49Ca and 47Ca, states arising by coupling a single particle to the 3− phonon of 48Ca are observed, showing the robustness of nuclear collectivity in rather light systems. The work demonstrates the feasibility of complete in-beam γ-spectroscopy with heavy-ion transfer reactions and provides a method that can be further exploited in the future with heavy targets and radioactive beams.
