Prevalence of Direct-Reaction Mechanism in a Deeply Inelastic ^<197>Au(^<19>F,^<12>B)

Continuum cross sections and spin polarizations of ^B produced in the reaction ^Au(^F, ^B) induced by 186-MeV ^F were measured. The observed data were reproduced very well in terms of a distorted-wave Born-approximation theory, indicating that this reaction transferring as many as seven nucleons proceeds as a direct process
