Inelastic proton scattering to the first excited 2+ state of the doubly magic ' Ni nucleus was investigated in inverse kinematics, using a secondary beam of radioactive Ni nuclei. At an incident energy of 101 MeV/nucleon, a value B(E2, 0+ 2+) = 600~120 e~fm4 was measured. This result completes the set of experimental data for the first excited 2+ states in the 1f 2p shell with a closed shell of neutrons or protons. These data are compared to recent shell-model calculations.

Angular distributions of the "Ge("0,"0)' Ge and "Ge(' 0, "0)"Ge reactions have been measured at incident energies of 75 and 77.6 MeV, respectively. The time-reversed reaction cross sections leading to the Ge ground states are nearly identical bell shaped curves. Stripping and pickup angular distributions to the Ge 2+ states show a strong shape difference suggesting interference between direct and two-step transfer.Angular distributions for which "0 is in its first 2+ state are similar in shape to those with "0 in its ground state. Data are also presented for elastic and inelastic scattering in both entrance and exit channels as well as for single-neutron transfer. NUCLEAR REACTIONSGe( 0 0), ( 0, 0) (80 0)E=75MeV; Ge( 0, 0), ( 0, 0) F.=77.6 MeV; measured o(0).

We have measured production yields and longitudinal momentum distributions of projectilelike fragments in the reaction 129 Xeϩ 27 Al at an energy of E lab ϭ790A MeV. Production cross sections higher than expected from systematics were observed for nuclei in the neutron-deficient tails of the isotopic distributions. A comparison with previously measured data from the fragmentation of 136 Xe ions shows that the production yields strongly depend on the neutron excess of the projectile with respect to the line of ␤ stability. The momentum distributions exhibit a dependence on the fragment neutron-to-proton ratio in isobaric chains, which was not expected from systematics so far. This can be interpreted by a higher excitation of the projectile during the formation of neutron-deficient fragments. ͓S0556-2813͑98͒02507-2͔PACS number͑s͒: 25.70.Mn
