We report preliminary data on proton-lambda correlations at small relative momentum q in the e 3He(4He) → e'pΛX reaction at E 0 = 4.7(4.46) GeV using the CLAS detector at Jefferson Lab. The enhancement of the correlation function at small q was found to be in qualitative agreement with theoretical expectations. The size of emission region about 1.5 fm was estimated using Lednický-Lyuboshitz analytical model. The experimental correlation function is comparable with the P-matrix fit of the hyperon-nucleon data. Small-relative-momentum-proton-lambda correlations both for 3He(4He) target and for electroproduction reaction were studied for the first time.
