Electron beam excitation studies of helium
A comparison is made of relative number densities of excited states produced in Helium gas excited by an RF discharge and by the high energy (200kev, maximum) electron beam, it being found that the 33D states are relatively ...
A method of polarization analysis of electrons from optically pumped He_
An experiment in progress to extract a polarized beam of electrons from an optically pumped helium source gas is described. Possible ionization mechanisms in helium gas are outlined and the methods of optical pumping are ...
