Deep-inelastic reaction - a new tool for nuclear spectroscopy

Binary reaction products of 92Mo + 60Ni, 106Cd + 54Fe, 124Sn + 80Se, 208Pb + 64Ni and 160Gd + 36S,37Cl heavy ion collision 10-15% above the barrier have been studied in γ-ray thick target experiments. The product yield distribution have been obtained for some of the reaction from γ-γ coincidence intensities as well as from target radioactivity measurements. The mass transfer between colliding nuclei is discussed in terms of mass and charge equilibration processes. These deep inelastic processes were found to populate a large number of neutron-rich nuclei strongly enough for yrast spectroscopy studies. New spectroscopic results are presented for the sdf shell nuclei 33Si, 34P, 39Cl for 64,65,66,67Ni products and for heavy tin isotopes 119,121,122,123,124Sn. Also yrast excitation in the 68Ni have been identified showing a substantial subshell closure at neutron number N=40. (author). 14 refs, 11 figs
