The angular distributions of deuterons from the reaction ⁶Li(¹²C,d)¹⁶O* leading to the ground state and first eight excited states of ¹⁶O have been measured at a center of mass energy of 7MeV. The angular distributions of deuterons leading to the third, fourth, and fifth excited states have been also measured at 8 MeV, and excitation functions for these levels at θLAB = 30° and 50° have been taken for these levels from 6 to 8 MeV. The results have been analyzed by calculating a theoretical contribution to the total cross sections due to the formation and decay of the compound nucleus ¹⁸F in a statistical region of excitation by a Hauser-Feshbach calculation. This contribution is then subtracted from the total, neglecting any interference effect, and the difference is related to a reduced alpha width of the ¹⁶O final states that might be measured in a purely direct alpha transfer reaction. The astrophysical significance of the reduced alpha width of the fourth excited state is discussed.
