We present a free-space interferometer to observe two-particle interference
of a pair of atoms with entangled momenta. The source of atom pairs is a
Bose--Einstein condensate subject to a dynamical instability, and the
interferometer is realized using Bragg diffraction on optical lattices, in the
spirit of our recent Hong--Ou--Mandel experiment. We report an observation
consistent with an entangled state at the input of the interferometer. We
explain how our current setup can be extended toenable a test of a Bell
inequality on momentum observables.
