An apparatus for the precise determination of lifetimes of atomic states.
The time which elapses between excitation of an atom by a pulse of light and subsequent emission of radiation may be measured by a delayed coincidence technique. A system which is suitable for measuring lifetimes of atomic states in the range 10(-7)-10(-8) sec, employing a high speed Kerr shutter in conjunction with a time-to-pulse height converter and kicksorter, is described.
