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.

relaxation time

re·lax·a·tion time (τ),

the time required for the substrate in an enzymatic or chemical reaction to fall to 1/e of its initial value.

relaxation time

An MRI term for the post-excitation return of spins to their equilibrium distribution, in which there is no transverse magnetisation and the longitudinal magnetisation is at its maximum value and oriented in the direction of the static magnetic field. Transverse magnetisation decays toward zero after excitation at a characteristic time constant T2; longitudinal magnetisation returns toward equilibrium with a characteristic time constant T1.

re·lax·a·tion time

(τ) (rē'lak-sā'shŭn tīm) The time required for the substrate in an enzymatic or chemical reaction to fall to 1/e of its initial value.
