The conserved-vector-current (CVC) theory predicts a deviation from the allowed shape of the B/sup 12/ and N/sup 12/ beta spectra. The ratio of the shape factors of the two spectra is expected to have an energy dependence of (1.10 plus or minus 0.17)% per Mev. If the CVC hynothesis is not invoked, this ratio is estimated to be an order of magnitude smaller. The two spectra have been measured with a magnetic spectrometer and found to give for this ratio the value (1.30 plus or minus 0.31)% per Mev. The branching fraction of the N/sup 12/ decay to the 7.6-Mev state of C/sup 12/ has been determined to be (3.0 plus or minus 0.5)%. (auth)
