The ..gamma.. decays of the levels at 17.77 and 18.36 MeV in /sup 12/C are studied by proton capture and the assignments of (0/sup +/,1) and (3/sup -/,1), respectively, are confirmed. The very great strength of the decay of the (0/sup +/,1) level to the lower (1/sup +/,0) level at 12.71 MeV is consistent with a spin- and isospin-flip deuteronlike transition. The strong decay of the (3/sup -/,1) level to the lower (3/sup -/0,) level at 9.64 MeV is fairly typical of an analog to antianalog transition. The ..gamma..-decay widths of these levels are compared with shell-model calculations.
