Deviations are found from the Poisson statistics that would result from a classical current. For detection in a narrow frequency interval, the photocount distribution has the negative-binomial form of black-body radiation if this frequency interval is less than the mean current in the conductor. When electronic localization sets in, a different type of super-Poissonian photon statistics results.4 pages including 1 figure; equation (28) correctedMesoscale and Nanoscale PhysicsQuantum Physicstext
