The A(e,e'K+)X reaction has been investigated at Jefferson Laboratory. Data were taken for Q2 approx 0.35\,\rm GeV2 at a beam energy of 3.245 GeV for 1H,3He and 4He targets.
Evidence for Lambda-hypernuclear bound states is seen for 3,4He targets. This is the first time that the electroproduction of these hypernuclei has been observed.
