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.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
