On kinematics of (e, e'p) reactions

The problem of interpretation of the experimental data on electron quasi-elastic scattering in the A(e, e'p) (A - 1) reaction is considered. It is shown, that the existing contradictions in the experimental data on the 4He(e, e'p)T reaction are related to the following: the missing momentum pm, which is calculated from the momentum - energy conservation law should not be interpreted as a momentum p of an initial intranuclear nucleon. The method of extracting modified by introducing a kinematic correction p was applied supposing redistribution of the momentum transferred by an electron to an intranuclear nucleon when the nucleon is leaving the nucleus. The correction essentially improved the situation. In the first approximation the correction value can be extracted from the data on inclusive A(e,e') reaction. The considerations are illustrated by the 4He(e, e'p)T reaction example
