We investigated simultaneously the {sup 12}C(e,e{sup '}p) and {sup 12}C(e,e{sup '}pp) reactions at Q{sup 2}=2 (GeV/c){sup 2}, x{sub B}=1.2, and in an (e, e{sup '}p) missing-momentum range from 300 to 600 MeV/c. At these kinematics, with a missing momentum greater than the Fermi momentum of nucleons in a nucleus and far from the delta excitation, short-range nucleon-nucleon correlations are predicted to dominate the reaction. For (9.5{+-}2)% of the {sup 12}C(e,e{sup '}p) events, a recoiling partner proton was observed back-to-back to the {sup 12}C(e,e{sup '}p) missing-momentum vector, an experimental signature of correlations.
