fig. 4 Missing energy spectra from reference [10] for ⁴He(e,e'p)X for incident electron energy of 0.599 GeV. Both the two body peak and the multi-body brakeup can be seen. The arrow points to the expected location of the peak in the missing energy spectrum if the virtual photon is absorbed on a pair of nucleons. The other numbers in the figures refer to the missing momentum of either the two body peak or the bump in the continuum.
