The ${}_{}{}^3{}_{}{}^{}\mathrm{He}$${\mathrm{}(\mathrm{p},\mathrm{p}\mathrm{p})\mathrm{}}^2$H and ${}_{}{}^3{}_{}{}^{}\mathrm{He}$${\mathrm{}(\mathrm{p},\mathrm{p}\mathrm{p})\mathrm{}}^2$${\mathrm{H}}^{*}$ reactions were investigated in a kinematically complete experiment at $E_{\mathrm{p}}=136\mathrm{}$ MeV for three angle pairs. The cross sections as a function of relative n-p energy were analyzed and compared to plane-wave impulse approximation predictions using one-boson exchange and Reid soft-core potentials to obtain detailed information about the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ wave function. No clear preference was established for one potential over the other, but limits were established on the mixed symmetry component of the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ wave function.
