Abstract
The momentum-transfer dependence of the H and He knockout reactions from Li via exclusive electron scattering has been measured, and the two reactions are compared. In the absence of two-step processes, the ratio of the fivefold cross sections for these mirror reactions should simply scale by the ratio of the H and He electron-scattering cross sections. A significant deviation from this simple expectation is seen at low momentum transfer. Possible explanations for this dramatic difference in cross sections for these mirror reactions are discussed.
