    "abstract": "We have studied the interference of degenerate quantum gases in a vertical\noptical lattice. The coherence of the atoms leads to an interference pattern\nwhen the atoms are released from the lattice. This has been shown for a\nBose-Einstein condensate in early experiments. Here we demonstrate that also\nfor fermions an interference pattern can be observed provided that the momentum\ndistribution is smaller then the recoil momentum of the lattice. Special\nattention is given to the role of interactions which wash out the interference\npattern for a condensate but do not affect a spin polarized Fermi gas, where\ncollisions at ultra cold temperatures are forbidden. Comparing the interference\nof the two quantum gases we find a clear superiority of fermions for trapped\natom interferometry.",
