Abstract

Angular distribution measurements have been carried out on the γ-rays from ¹⁵N and ¹⁵O following the photodisintegration of ¹⁶O. A bremsstrahlung spectrum with 27 MeV endpoint was used, and measurements were taken at three angles, 90°, 120° and 150°. Values of the anisotropy coefficients a₂ a₀ were obtained for transitions through the states at 6.323, 5.299 and 5.270 MeV of ¹⁵N, and the 6.180 MeV state of ¹⁵O. The results for transitions to the 6.323 MeV state of ¹⁵N and the 6.180 MeV state of ¹⁵O produce revised values of the branching ratios to these states, and bring them into agreement with the estimates of Buck and Hill.
