Abstract

Continuum cross sections and spin polarizations of ${}^{12}B$ produced in the reaction ${}^{197}{Au}$ ( ${}^{19}F$ , ${}^{12}B$ ) induced by 186-MeV ${}^{19}F$ 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.
