Abstract
The polarizations, and , of the recoils (,)(g.s.) were measured simultaneously by selective recoil implantation. Their ratio is largely immune to the systematics of and and more dependent on the dynamics than either. Our result (normalized to unit ), , yields (impulse approximation) and (elementary-particle treatment), to be compared to partial conservation of axial-vector current (PCAC) predictions of 7 and - 0.99, respectively. Thus PCAC is quantitatively verified.
