Differential cross sections and {ital T}{sub 20} and {sup {ital T}}{ital T}{sub 20} analyzing powers have been measured for 70 MeV {sup 7}Li breakup into the {alpha} particle plus triton channel, on a {sup 120}Sn target. Measurements were made for both continuum breakup and sequential breakup via the 4.63 MeV state in {sup 7}Li. The {ital T}{sub 20} data for the continuum breakup do not agree with a semiclassical Coulomb model, indicating that the breakup at small angles does not proceed solely via a Coulomb force. The data generally show a somewhat better agreement with continuum discretized coupled channels calculations, indicating the importance of the nuclear force and channel coupling in the reaction mechanism.
