| Abstract: | Production cross sections for neutron-rich nuclei from the fragmentation of a 82 Se beam at 139 MeV/u were measured. The longitudinal momentum distributions of 122 neutron-rich isotopes of elements 11 ≤ Z ≤ 32 were determined by varying the target thickness. Production cross sections with beryllium and tungsten targets were determined for a large number of nuclei including several isotopes first observed in this work. These are the most neutron-rich nuclides of the elements 22 ≤ Z ≤ 25 ( 64 Ti, 67 V, 69 Cr, 72 Mn). One event was registered consistent with 70 Cr, and another one with 75 Fe. A one-body Q g systematics is used to describe the production cross sections based on thermal evaporation from excited prefragments. The current results confirm those of our previous experiment with a 76 Ge beam: enhanced production cross sections for neutron-rich fragments near Z = 20. |
