Quasifree A, Σ0, and Σ-electroproduction from 1,2H, 3,4He, and carbon

Kaon electroproduction from light nuclei and hydrogen, using 'H, 2 H, 3 He, 4 He, and carbon targets has been measured at the Thomas Jefferson National Accelerator Facility. The quasifree angular distributions of A and E hyperons were determined at Q 2 = 0.35 (GeV/c) 2 and W = 1.91 GeV. Electroproduction on hydrogen was measured at the same kinematics for reference.
