Reaction dynamics and nuclear structure studies via deep inelastic collisions with heavy-ions: Spin and parity assignment in ⁴⁹Ca

The population and gamma decay of neutron rich nuclei around 48Ca has been
measured at Legnaro National Laboratory with the PRISMA-CLARA setup, using deepinelastic collisions (DIC) on 64Ni, at an energy approximately twice the Coulomb barrier. The
reaction properties of the main products are investigated, focusing on total cross sections and
angular distributions both integrated in energy and associated to the population of specific
excited states. Gamma spectroscopy studies are also performed, giving evidence, for the first
time in transfer reactions with heavy ions, of a large spin alignment (~70%), perpendicular to
the reaction plane. This makes possible the use of angular distributions and polarization
measurements to firmly establish the spin and parity of excited states populated in nucleon
transfer channels, as in the case of 49Ca, where candidates for particle-core coupling are
investigated. Both reaction and gamma spectroscopy studies demonstrate the relevance of DIC
with heavy ions for a detailed investigation of moderately neutron rich systems.
