Angular distributions and total cross sections of the C^<12>(d, α)B^<10> and O^<16>(d, α)N^<14> reactions were obtained in the deuteron energy range from 15 MeV to 20 MeV. Deuteron energies were 15.1, 15.9, 16.7, 17.5, 18.2, 19.0 and 19.7MeV in the C^<12>(d, α)B^<10> reaction, and were 14.9, 15.4, 15.7, 16.0, 16.5, 16.9, 17.3, 18.1, 18.8 and 19.6MeV in the O^<16>(d, α)N^<14> reaction. Alpha particle groups leaving the residual nuclei in their low-lying states showed pronounced forward and backward peaks simultaneously in the vvhole energy range. Total cross sections decreased gradually with increasing deuteron energies, but some anomalies were found. Reaction mechanism is discussed under the assumptions of knock-out and heavy-particle stripping processes, and it is indicated that the clustering of nucleons at the surface of the target and or the residual nuclei seems to play an important role in these reactions.
