Abstract
The T20 analyzing powers have been measured for the 120Sn(7Li, 8Be → 2α) 119In and 120Sn(7Li, 6Li* → α + d) 121Sn transfer breakup reactions, using a 70 MeV beam. The data exhibit excellent agreement with the results of coupled reaction channels calculations, providing an important test of these calculations when applied to the transfer breakup reaction mechanism.
