Abstract
Differential cross sections for elastic \(p{}^{3}\)He scattering at energies in the range of \(156\leq T_{p}\leq 1000\) MeV and proton analyzing powers of this process are calculated on the basis of the Glauber diffraction model with allowance for the spin dependence of nucleon–nucleon amplitudes. Explicit expressions are obtained for the first time for all six invariant amplitudes of \(p{}^{3}\)He scattering for the mechanisms of single, double, and triple incident-proton scattering off target nucleons. Good agreement with experimental data is found both for the cross sections and for spin observables in the forward hemisphere of scattering angles. Also, explicit expressions are obtained for \(p{}^{3}\)He-scattering amplitudes violating time-reversal (\(T\)) invariance but preserving spatial parity (\(P\)). These expressions can be used in testing \(T\) invariance in this and other processes.
