Abstract
We study current fluctuations in a single tunnel junction. The effect of external leads and of the Coulomb interaction is incorporated in th e calculation. We obtain the fluctuations at the tunneling barrier of the junction and at the leads. It is shown that the two fluctuations h ave different noise spectra, and that the relation between them is non trivial. The origin of the difference is discussed and the results are compared with recent experiments.
