摘要：

We have measured missing-energy spectra for the reaction C12(e,ep) in the quasielastic region in parallel kinematics at momentum transfers q of 585, 775, and 827 MeV/c. We observed 1p and 1s single-proton knockout peaks and large broad strength attributed to multinucleon knockout. We saw no increase in strength at pion threshold. The ratio of single-particle knockout to a distorted-wave impulse-approximation calculation is approximately constant with q. Multinucleon knockout is 25%"40% of the total cross section; it increases with q. This quasielastic non-single-nucleon knockout is much stronger than previously observed. © 1990 The American Physical Society.
