Abstract
The differential cross section for the reaction was measured from 31° to 149° c.m. with an 82-MeV -beam. The measurements were made to test the Barshay-Temmer theorem which requires and yields to be independently symmetric about 90° c.m. We find a pronounced and angle-dependent deviation from 90° symmetry, as large as 10% at some angles. Our results thus constitute the first clear-cut evidence for a violation of the above theorem.
