Probing for high momentum protons in He via the reaction
Experimental cross sections for the reaction up to a missing
momentum of 0.632 GeV/ at and =2(GeV/) are reported.
The data are compared to Relativistic Distorted Wave Impulse
Approximation(RDWIA) calculations for channel. Significantly
more events in the triton mass region are measured for >0.45 GeV/
than are predicted by the theoretical model, suggesting that the effects of
initial-state multi-nucleon correlations are stronger than expected by the
RDWIA model

Probing for high-momentum protons in He 4 via the He 4 (e,e′p)X reactions
Experimental cross sections for the He4(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 He4(e,e′p)H3 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
