relaxation time

(ree-laks-ay -shŏn) The time taken for the velocity of an object in a multiple-body system to become similar to the velocity of others in that system, and hence for the total system to become smooth and regular. See dynamical relaxation.

relaxation time

[‚rē‚lak′sā·shən ‚tīm]
(physics)
For many physical systems undergoing relaxation, a time τ such that the displacement of a quantity from its equilibrium value at any instant of time t is the exponential of -t /τ.
(solid-state physics)
The travel time of an electron in a metal before it is scattered and loses its momentum.
