The ${}_{}{}^1{}_{}{}^{}\mathrm{H}({}_{}{}^6{}_{}{}^{}\mathrm{He}, {}_{}{}^6{}_{}{}^{}\mathrm{Li})n$ reaction was studied at 0° with the NSCL A1200 fragment separator in the energy loss mode. A ${}_{}{}^6{}_{}{}^{}\mathrm{He}$ secondary beam at $\frac{E}{A}=93\mathrm{}$ MeV was used to measure the Gamow-Teller and Fermi strengths between the ground state of ${}_{}{}^6{}_{}{}^{}\mathrm{He}$ and the ground and excited states of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, in inverse kinematics. At 0° the ground-state cross section is measured to be $\frac{d{\sigma }_{\mathrm{GS}}}{\left(d\Omega \right)}=43\mathrm{}\pm 16$ mb/sr, which is dominated by systematic error in the secondary beam flux. The ratio of Gamow-Teller to Fermi strength is not sensitive to this error and is found to be (87±6)% of that expected from ($p, n$) systematics and $\beta$ decay. Angular distributions have been measured between 0° and 10° in the center of mass.
