Description
The replacement of the N=20 spherical shell gap in nuclei of the island of inversion
by the N=14,16 gaps can be explained by the tensor monopole interaction between the
proton and neutron Fermi levels. The next step in understanding the evolution of
shell structure is to measure the strengh of this interaction, which is present
throughout the nuclear chart. The ideal tool for this are transfer reactions where
single-particle energies and spectroscopic factors can be extracted. Hence it is our
aim to measure the neutron d3/2 strength function in nuclei where protons are
gradually filling the d5/2 state (oxygen, neon, magnesium and silicon) by (d,p)
reactions in inverse kinematics. Part of this program could be done at Rex-Isolde
once the energy upgrade to 5 MeV/u is in place.
