Formation and decay of argon and xenon molecules radiating in the vacuum ultraviolet
The time dependence of the vacuum ultraviolet emission from dense (1-3 atm) argon and xenon is measured following excitation by a low intensity electron beam. Independent radiation is observed from the lowest excited 1Q ...
Electron spin polarization in low energy electron diffraction
Substantial electron spin polarization has been observed in low energy electron diffraction (LEED) from the (1) surface of tungsten. The electron polarization is determined by directing a fraction of the elastically ...
