Notes:
Laser-induced fluorescence has been used to measure the velocity, direction, and divergence of a beam of neutral hydrogen atoms traveling at 50 MeV or one-third the speed of light. The beam was produced by neutralizing a negative hydrogen ion beam in a foil stripper, which generated a fraction of the atoms in the metastable 2s state. These metastables were measured by pumping the 2s to 3p transition with a flashlamp pumped dye laser at 623 nm and detecting fluorescence in the vacuum ultraviolet from the 3p to 1s ground-state transition.
