Calculations of the ${}_{}{}^4{}_{}{}^{}\mathrm{He}\mathrm{}(p,2p)\mathrm{}{}_{}{}^3{}_{}{}^{}\mathrm{H}$ reaction in the distorted-wave impulse approximation do not reproduce the experimental data. The recent agreement obtained using a less sophisticated reaction model would seem to arise from the use of total cross sections which are too large.
