Investigating the dynamics of ion-surface interactions using electron-spin-polarized positively charged helium ions
Spin-labeling techniques, specifically using electron-spin-polarized 4He+ ions coupled with energy-resolved measurements of the polarization of ejected electrons, are providing significant insight into surface electronic ...
A low-energy, electron-spin-polarized helium(+) ion source for use in surface studies
A spin polarized He$\sp+$ ion source has been developed to study the dynamics of ion-surface interactions. The He$\sp+$ ions are produced by Penning ionization in collisions between electron-spin-polarized He(2$\sp3$S) ...
