Electron scattering from C was measured at a momentum transfer of 5.08 fm . No electron events were observed in the vicinity of the elastic peak, giving an upper limit for the elastic cross section of 1.2 x 10 cm /sr with a confidence level of 90%. At this momentum transfer, the square of the elastic M1 form factor apparently continues to fall exponentially with q. Comparison of the data with shell-model calculations indicates that admixtures of 2hu configurations in the C ground state cannot entirely explain the high-q enhancement of the Ml form factor relative to 1p-shell calculations.
