O138900100013 COMMENT -By authors. Two separate runs were performed: O138900100014 1. Measurement of angular distribution at E(lab)=4-MeVO138900100015 between 10- and 70-degree in laboratory system. Three O138900100016 telescopes, separated by 20-degree, were used O138900100017 simultaneously. O138900100018 2. Measurement of three-point angular distribution O138900100019 at E(lab)=3, 5, 6, 7, 8-MeV and angle=10, 35, 70- O138900100020 degree.
