The forward-backward asymmetry of recoil nuclei from the reaction Al/sup 27/(n, alpha )Na/sup 24/ was investigated by the recoil technique. On polyethylene foils placed in forward (F) and backward (B) directions, the recoil nuclei emitted into intervals O/sub BETA / - rature of the d /2 and rature of the d /2- rature of the d , respectively, were captured. The BETA -activity ratio of the Na/sup 24/ upon the forward and backward foils (A/sub F//A/sub B/) was measured as a function of the thickness of the aluminum foil and extrapolated to 0-thickness. The value 5.1 ction in DDT-C/ 0.3 was obtained. (C.E.S.)
