It is shown that the second gauge condition selects out a unique member from each K-degenerate family. The vector so selected is not, in general, normalizable, but finite results can be obtained after renormalization. Calculation of norms and vertex functions is examined and is shown to be perfectly feasible. (Author) 收起
