The 1H(6He, 6Li)n reaction was studied at 0° with the NSCL A1200 fragment separator in the energy loss mode. A 6He secondary beam at E/A=93 MeV was used to measure the Gamow-Teller and Fermi strengths between the ground state of 6He and the ground and excited states of 6Li, in inverse kinematics. At 0° the ground-state cross section is measured to be dσGS/(dΩ)=43±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 β decay. Angular distributions have been measured between 0° and 10° in the center of mass.
