Angular Distributions For H-3,4(Lambda) Bound States In The He-3,He-4(E,E(')K(+)) Reaction

The H-3,4(Lambda) and H-4(Lambda) hypernuclear bound states have been observed for the first time in kaon electroproduction on He-3,He-4 targets. The production cross sections have been determined at Q(2)=0.35 GeV2 and W=1.91 GeV. For either hypernucleus the nuclear form factor is determined by comparing the angular distribution of the He-3,He-4(e,e(')K(+))(Lambda)H-3,H-4 processes to the elementary cross section H-1(e,eK(+))Lambda on the free proton, measured during the same experiment.
