Optical manipulation of helium(2(3)S) atoms with a diode laser
A commercial Spectra Diode Laboratories, 1.083 $\mu$m diode laser has been used to efficiently spin polarize an atomic beam of He(2$\sp3$S) metastable atoms by optical pumping on the $\rm 2\sp3S\sb1\rightarrow2\sp3P\sb1$ ...
The dynamics of neutralization of electron-spin-polarized (4)He(+) ions at surfaces
Ion Neutralization Spectroscopy (INS) is a well known probe of surface electronic structure with unparalleled surface specificity. In INS, a beam of singly-charged low-energy rare gas ions is directed at a target surface, ...
