We have measured the transverse and the longitudinal polarization transfer coefficients $K_y^{y\mathcal{’}}$ and $K_z^{z\mathcal{’}}$ at 0° in the (p,n) reactions from ${}_{}{}^6{}_{}{}^{}$,7Li and ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ for proton energies near 55 MeV. Except for the ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$(p,n)Be reaction, where $K_y^{y\mathcal{’}}$(0°)=-0.33±0.04, all transfer coefficients are <0.20 and thus not very suitable for the production of polarized neutrons.
