Abstract

Significant differences between the polarization, $P$ , and analyzing power, $A$ , have been measured in the reaction ${}^{12}C (p, p^{'}) {}^{12}C (1^{+} states)$ at $E_{p} = 150$ MeV. It is shown that $P - A$ is different from zero primarily because of that part of the tensor exchange amplitude associated with the transferred quanta, $l s j = 111$ , to the nucleus. This amplitude determines a combination of transition density matrix elements for the 15.11-MeV state that is largely undetermined from other experiments.
