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.
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
Double-differential cross sections have been measured for inclusive (p, p') reactions on targets of Y, Zr, and the even-mass Mo isotopes from A = 92 to 98 at incident proton energies of 120, 160, and 200 MeV. Comparisons are made with calculations based on the statistical multistep direct theory of Feshbach, Kerman, and Koonin. In general it is found that the theory gives a good description of the angular distributions. Possible explanations for the deviation of the predicted cross sections from experiment at very low and very high excitation energies of the residual nucleus are given.PACS number(s): 24.60. Gv,
The spins and electromagnetic properties of levels in 45Sc up to 2,352 keV were studied by means of inelastic proton scattering using a 3-parameter coincidence arrangement and Coulomb excitation with 3He and 4He beams. Relevant experimental results are discussed in terms of the Thankappen-True core-plus-particle model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
