Abstract

The hypernuclear bound states of _λ^3,4H nad _λ⁴H in kaon electroproduction on ^3,4He targets were analyzed. The production cross sections were determined at Q ² = 0.35 GeV² and W = 1.91 GeV. The production of the bound hypernuclei _λ³H was obtained in the electroproduction and angular distribution for ^3,4He(e,e′K)_λ^3,4H processes was also obtained using reaction spectroscopy. The results show that the angular distribution for ³He was observed to be flatter as compared to ⁴He at large angles.
