Abstract
To investigate the applicability of the Butler stripping theory, the angular correlations have been measured between the protons and rays from the reactions (3.37 Mev) and (1.95 Mev), using 7.78-Mev deuterons. Both correlations in the () plane are of the form , where is the angle between the ray and the recoil nucleus, as predicted by theory. For the coefficient , in reasonable agreement with the previously reported value of -0.40±0.05 for a deuteron energy of 4 Mev, and hence confirming the theoretically expected energy independence. This value of is close to that of -0.40 predicted on the assumption of coupling with the assignment of a state for the first excited level of . For , , in satisfactory agreement with the predicted value of 0.143 obtained by using the reasonable assumption of coupling with less than % in the predominantly transition. Both transitions showed less than 6% effect in the correlation in the plane perpendicular to the recoil axis, in agreement with the isotropy expected from the simplified stripping theory.
