Levels up to 9.3 MeV excitation in 22Ne were studied with the 19F(c~, p~/) 22Ne reaction at E~ = 12 MeV. Level energies, branching ratios, mean lifetimes, spins and mixing ratios were obtained for a number of levels.Relevant results are compared with many-particle shellmodel calculations.

Results of reaction cross-section measurements on 12 C, 40 Ca, 90 Zr, and 208 Pb at incident proton energies between 80 and 180 MeV and for 58 Ni at 81 MeV are presented. The experimental procedure is described, and the results are compared with earlier measurements and predictions using macroscopic and microscopic models.

Measurements of inclusive ( p,␣) reactions on 27 Al, 59 Co, and 197 Au at incident energies between 120 and 200 MeV are compared with the trend expected from systematics and also with calculations based on a statistical multistep direct reaction theory. Although reasonable agreement is obtained between the experimental angular distributions and the predictions of the parametrized systematics at various emission energies, significant discrepancies are nevertheless observed. Calculations with the quantum-mechanical multistep formulation confirm that the higher-step contributions are more important at these incident energies than found in a previous study at lower projectile energies. ͓S0556-2813͑96͒03007-5͔
