Spectra of d..cap alpha.. coincidences have been measured in the reactions /sup 12/C(/sup 6/Li,d)/sup 16/O(..cap alpha..)/sup 12/C and /sup 16/O(/sup 6/Li,d)/sup 20/Ne (..cap alpha..)/sup 16/O at lithium-ion energies 60, 75, and 90 MeV. In coincidence spectra corresponding to the interval 30--50 MeV of excitation energy of /sup 16/O and /sup 20/Ne nuclei, no manifestations were observed of the existence of ..cap alpha..-cluster levels built on the ground states of /sup 12/C and /sup 16/O. The results of the measurements may indicate existence in /sup 16/O of ..cap alpha..-cluster levels in the interval 32--36 MeV built on the first two excited states of /sup 12/C.
