title: Pair-correlation properties and momentum distribution of finite number of interacting trapped bosons in three dimensions.
abstract: We study the ground state pair-correlation properties of a weakly interacting trapped Bose gas in three dimensions by using a correlated many-body method. The use of the van der Waals interaction potential and an external trapping potential shows realistic features. We also test the validity of shape-independent approximation in the calculation of correlation properties.
