摘要: The 3Lambda H and 4Lambda hypernuclear bound states have been observed for the first time in kaon electroproduction on 3,4He targets. production cross sections determined at Q**2= 0.35 GeV**2 W= 1.91 GeV. For either hypernucleus nuclear form factor is by comparing angular distribution of 3,4He(e,e'K+)3,4Lambda processes to elementary section 1H(e,e'K+) Lambda free proton, measured during same experiment.
