Usinga model many-body wave function I analyze the standard criterionfor Bose-Einstein condensation and its relation to coherence properties ofthe system. I pay special attention to an attractive condensateunder such a condition that a characteristic length scale ofthe spatial extension of its center of mass differs significantlyfrom length scales of relative coordinates. I show that althoughno interference fringes are produced in the two-slit Young interferenceexperiment performed on this system, fringes of a high visibilitycan be observed in a conditional simultaneous detection of twoparticles.
