Proton-deuteron elastic large angle scattering cross sections, noting backward peak consistent with baryon exchange mechanism with resonance transfer

The differential cross section for elastic scattering of 600-MeV protons from $^{4}\mathrm{He}$ has been measured for laboratory angles between 4\ifmmode^\circ\else\textdegree\fi{} and 44\ifmmode^\circ\else\textdegree\fi{}. The data are analyzed in terms of the diffraction approximation of Glauber.

Cross sections measured for symmetric /p, 2p/ reactions on deuterium and He, discussing nonsymmetric /p, 2p/ events in He

Thirteen angular distributions have been measured from 8\ifmmode^\circ\else\textdegree\fi{} to 70\ifmmode^\circ\else\textdegree\fi{} for the ${\mathrm{Sc}}^{45}(\ensuremath{\alpha},t){\mathrm{Ti}}^{46}$ reaction at 41 MeV. Very selective population of the states of ${\mathrm{Ti}}^{46}$ was observed, and the populated states correlate well with states of the ${\mathrm{Sc}}^{45}({\mathrm{He}}^{3},d){\mathrm{Ti}}^{46}$ reaction which have large ${l}_{p}=3$ spectroscopic strengths. The angular distributions have little structure and exhibit the same basic shape. The distorted-wave Born-approximation (DWBA) noncutoff calculations for the stripping of an ${l}_{p}=3$ proton provides an adequate description of the angular distributions. The relative spectroscopic strengths extracted from the DWBA analysis agree favorably with those deduced from a similar study of the ${\mathrm{Sc}}^{45}({\mathrm{He}}^{3},d){\mathrm{Ti}}^{46}$ reaction. Theoretical spectroscopic strengths calculated from the McCullen-Bayman-Zamick single-particle wave functions for the ground state of ${\mathrm{Sc}}^{45}$ and five low-lying states of ${\mathrm{Ti}}^{46}$ are in reasonable agreement with experiment.
