The {sup 1}H({sup 6}He,{sup 6}Li){ital n} reaction was studied at 0{degree} with the NSCL A1200 fragment separator in the energy loss mode. A {sup 6}He secondary beam at {ital E}/{ital A}=93 MeV was used to measure the Gamow-Teller and Fermi strengths between the ground state of {sup 6}He and the ground and excited states of {sup 6}Li, in inverse kinematics. At 0{degree} the ground-state cross section is measured to be {ital d}{sigma}{sub {ital GS}}/({ital d}{Omega})=43{plus_minus}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{plus_minus}6){percent} of that expected from ({ital p},{ital n}) systematics and {beta} decay. Angular distributions have been measured between 0{degree} and 10{degree} in the center of mass. {copyright} {ital 1996 The American Physical Society.}
