Abstract
() angular distributions have been measured along with () correlations in , , and in order to test the applicability of stripping correlation theory and assign tentative quantum numbers. Deuteron energies were 2.5 to 4 Mev. All correlations exhibited the predicted deuteron energy independence and approximate angular symmetry in the () plane at energies above 3.5 Mev. The correlation was shown to be isotropic to ±7% in the plane perpendicular to the axis of the recoil nucleus. The observation of a () stripping peak 2 or 3 times the minimum yield is not a sufficient criterion for the observation of a correlation which is independent of deuteron energy. All correlations were of the form (gamma, recoil nucleus). The observed were -0.50, 0.00, +0.50, -0.40, for (3.37 Mev), (4.46 Mev), (6.76 Mev), (3.40 Mev), respectively. All uncertainties in were ±0.05. Spin ½ is ruled out for (3.40 Mev). The anisotropy is within 15% of one extreme of theoretically possible anisotropies. The incoming channel spin mixing ratio found in can be gotten by assuming pure coupling and a level. The spin is unlikely for the (4.46 Mev) level, while the spin is ruled out and is unlikely for the (6.76 Mev) level.
