Abstract
We study analytically the structure of an arbitrary-order correlation function for a pair of Fock states and prove without any approximations that, in a single measurement of particle positions, interference effects must occur as experimentally observed with Bose-Einstein condensates. We also show that the noise level present in the statistics is slightly lower than for a corresponding measurement of phase states.
