Microscopic Analysis of Proton Scattering from 28Si at 22MeV

  • The 28Si(p, p)and (p, p') reactions were studied with a 22 MeV proton beam.The differential cross sections for elastic scattering and inelastic scattering from 21+(1.78 MeV) and 41+(4.62 MeV) excited states were measured and compared with the results based on momentum space DWBA theory.A complex density-dependent and energy-dependent effective interaction(CEG) and transition densities obtained from electron scattering were used in the calculations. The present parameter-free calculations provide a satisfactory description of the low-energy proton scattering data on 28Si.

Abstract: The 28Si(p, p)and (p, p') reactions were studied with a 22 MeV proton beam.The differential cross sections for elastic scattering and inelastic scattering from 21+(1.78 MeV) and 41+(4.62 MeV) excited states were measured and compared with the results based on momentum space DWBA theory.A complex density-dependent and energy-dependent effective interaction(CEG) and transition densities obtained from electron scattering were used in the calculations. The present parameter-free calculations provide a satisfactory description of the low-energy proton scattering data on 28Si.
