Abstract
The decays of neutron-rich Ca isotopes around Ca were measured at Legnaro National Laboratory with the PRISMA-CLARA setup, using the heavy-ion transfer reactions Ca on Ni and Ca on Pb at 6 MeV/A. The work shows the feasibility to perform full in-beam spectroscopy with heavy-ion transfer reactions (in terms of angular distributions, polarizations, and lifetimes analysis), providing a method that can be further exploited in the future with heavy targets and radioactive beams. For the one-neutron transfer channels, Ca and Ca, shell-model and particle-vibration coupling calculations are used to understand the nature of the states. In particular, in both nuclei evidence is found for particle-vibration coupled states based on the 3 phonon of Ca. In the two-neutron transfer channels, Ca and Ca, the experimental data are in global agreement with predictions based on full shell-model calculations.
