Spin polarized metastable He*(2(3)S, 1s2s) stimulated desorption of H(+) ions.
The yield of H(+) in the metastable He*(2(3)S, 1s2s) stimulated desorption (MSD) on an H2O/Na/Fe surface has been found to depend on the spin of the incident He*. By combination with the spin-resolved analysis for the surface electronic structure, it is indicated that the neutralization of the hole in the OH 3 sigma molecular orbital, which is created by the incident He*, by Na 3s electrons plays a crucial role in the spin polarization of the H (+) MSD intensity. The dependence of the spin polarization of H(+) MSD on the kinetic energy of the desorbed H(+) has been observed, and it is discussed based on the Menzel-Gomer-Readhead model.
