Angular distributions of the alpha particle transfer reaction [sup 12]C([sup 11]B,[sup 7]Li)[sup 16]O were measured for 28, 35, 40, 50, 56, 60, and 80 MeV beam energies. Exact finite range distorted-wave Born approximation (DWBA) analysis was performed for eight states of [sup 16]O: ground state, 6.13 MeV (3[sup [minus]]), 6.92 MeV (2[sup +]), 10.36 MeV (4[sup +]), 11.10 MeV (4[sup +]), 14.82 MeV (6[sup +]), 16.28 MeV (6[sup +]), and 20.86 MeV (7[sup [minus]]). Values of spectroscopic factors were extracted. For low lying states they agree well with theoretical shell model predictions. No evidence for tetrahedral deformation of the [sup 16]O ground state was found.
