Summary
We performed gamma-ray spectroscopic studies of deep-inelastic reaction products by combining the coincidence thick target technique with the CLARA+PRISMA identification method. Such approach turned out to be very successful in locating yrast structures in hard-to-reach neutron-rich nuclei.
By identifying high spin states in 52Sc and 51Ca, we were able to get information on the evolution of the neutron p3/2, p1/2 and f5/2 single particle states down to Z=20. This evolution seems to be consistent with the predicted monopole effect of the tensor force.
