OSTI ID:954439
The cross section of the 4He(e,e'p)3H reaction has been measured for missing momenta 220<= pm <= 690 MeV/c to study high-momentum components of the nuclear wave function and the reaction mechanism for this transition. The zero predicted in the plane-wave impulse approximation (PWIA) cross section, due to the underlying pt momentum distribution, is found to be washed out. Three types of calculations indicate that this is caused by final-state interactions and contributions from two-body currents. The calculations reproduce the high pm (600-690 MeV/c) data, although due to different ingredients in the models.
