Angular distributions of neutrons corresponding to transitions to the first (2.31 Mev) and second (3.95 Mev) excited states in the reaction ${\mathrm{C}}^{13}(d, n){\mathrm{N}}^{14}$ have been measured at an incident deuteron energy of 1.3 Mev. A time-of-flight technique utilizing the associated gamma ray as a trigger was employed to separate the various neutron groups. Because the data, particularly for the first excited state transition, exhibited a relatively large intensity in the backward direction, a simple deuteron-stripping process is not sufficient to account for the results. An analysis which included the heavy-particle stripping mode was consistent with the data.
