  22. Summary We performed gamma-ray spectroscopic studies of deep-inelastic reaction productsby combining the g-g coincidencethick target techniquewith 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.
