Abstract

The proton differential cross section and polarization in p-α scattering have been measured at 12 lab scattering angles from 20° to 155° for proton energies between 22 and 25 MeV. The resonance corresponding to a 32+ state of 5Li is clearly observed. An energy-dependent phase-shift analysis of most of the available p-α scattering data between 20 and 27.8 MeV was made.

The energy dependence of the phase shifts was expressed in term of the resonance parameters with the Breit-Wigner single-level formula for the resonant part, and it was assumed to be linear for the non-resonant part. The resonance is well reproduced for both cross section and polarization.
