The energy spectra of deuterons from the ${\mathrm{C}}^{12}(\alpha , d){\mathrm{N}}^{14}$ reaction have been studied up to an excitation of 21 MeV. The reaction was induced by 53-MeV alpha particles from the Berkeley 88-in. spiral-ridge cyclotron, and the reaction products were distinguished by a new type of particle identifier. The observed selectivity of final state population is correlated with the predicted configurations for many ${\mathrm{N}}^{14}$ levels and several new assignments are made.
