Physical Review C
Experimental cross sections for the 4He(e,e′p) X reactions in the missing energy range from 0.017 to 0.022 GeV and up to a missing momentum of 0.632 GeV/c at xB = 1.24 and Q2 = 2 (GeV/c)2 are reported. The data are compared to relativistic distorted-wave impulse approximation calculations for the 4He(e,e′p)3H channel. Significantly more events are observed for pm ≥ 0.45 GeV/c than are predicted by the theoretical model, and striking fluctuations in the ratio of data to the theoretical model around pm = 0.3GeV/c are possible signals of initial-state multinucleon correlations.
