  We performed measurements of Quantum Shot Noise in order to determine the
quasiparticle charge in the Fractional Quantum Hall regime. The noise is
generated by a current flow through a partially transmitting Quantum Point
Contact in a 2DEG. The noise is directly proportional to the charge of the
quasiparticles, thus allowing direct determination of the charge. We measured
Quantum Shot Noise at a filling factor of 1/3 and found that the charge is e/3;
as predicted by Laughlin.
