Abstract

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.
