Description

Transfer reactions provide a powerful and selective tool to probe the
microscopic structure of atomic nuclei. In particular, they are
sensitive to single-particle occupancies and wave-function overlaps,
offering direct insight into the interplay between single-particle and
collective degrees of freedom. This makes them ideally suited to
investigate shape coexistence in nuclei.
In this talk, I will give a brief introduction to transfer reactions and
discuss recent measurements using radioactive ion beams. Special
emphasis will be placed on two-neutron transfer reactions, which are
particularly sensitive to shape coexistence and configuration mixing. I
will outline future prospects for transfer-reaction studies at
next-generation facilities, with a focus on the ARIEL project at TRIUMF.
The increased beam intensities and extended isotope reach will open new
opportunities for systematic investigations of shape coexistence in
neutron-rich nuclei.
