Proton Source Size Measurements in the eA→e'ppX Reaction
Abstract
Two-proton correlations at small relative momentum q were studied in the eA(3He,4He,C,Fe)→e'ppX reaction at E0=4.46 GeV using the CLAS detector at Jefferson Lab. The enhancement of the correlation function at small q was found to be in accordance with theoretical expectations. Sizes of the emission region were extracted, and proved to be dependent on A and on the proton momentum. The size of the two-proton emission region for He was measured in eA reactions for the first time.
