The difference between the polarization and analyzing power for the reaction ${}_{}{}^3{}_{}{}^{}\mathrm{He}\mathrm{}(p,n)\mathrm{}{}_{}{}^3{}_{}{}^{}\mathrm{He}$ has been calculated in a $4\hslash \omega$ model space within the framework of the generalized $R$-matrix method of Lane and Robson. The model calculations indicate neither the presence of $f$ wave components nor a significant sensitivity of the $P-A$ difference to the position of the ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ levels.
