Abstract

The differential cross sections for antiproton elastic scattering on ⁴He at 192.8 MeV/c are measured. The annihilation cross section σ_a = (377.6 ± 8.0) mb, the elastic cross section σ_el = (206.3 ± 6.6) mb and the total p⁴He interaction cross section σ_tot = (583.9 ± 10.4) mb are determined. The ratio of the real to imaginary part of the forward p⁴He amplitude is found: π=-0.17±_0.33^0.24. Partial wave analysis reveals that the S, P and D waves are essential in this energy region.
