Abstract ： Integrated Stokes parameters Pi (i=1,2, 3) for the He 3 3 P → 2 3 S1 (388.9nm) transition after excitation from the ground state to the 3 3 P state by a transversely spin-polarized electron beam are measured in near threshold energy region. The experimental results are presented. The linear-polarization P2 are consistent with zero over the incident energy range, providing evidence for the LS coupling mechanism of the 3 3 P state. The measured circular polarization P3 are non-zero, indicating strong electron-electron exchange effects in the spin-polarized electron-atom collision process.
