approaches its maximum asymptotically, whereas in our confined three dimensional case, it vanishes asymptotically. When A is increased to 2470, which is very close to the critical number ( A$_{cr}$ ≃ 2475), the effect is quite prominant. As the width of the curves decrease with increase in effective attractive interaction, the interacting pair becomes more localized. This manifests the possiblity of clustering due to large two-body interaction and three- body recombination, if the attraction becomes strong enough. This will lead to an eventual collapse of the attractive condensate, when the pair-correlation length will drastically reduce to a very small value and the condensate will be destroyed. Two-particle correlation is directly related with pair inelastic processes and can be di- rectly measured in photoassociation in interatomic collisions. As the attractive interaction increases, the gas becomes highly correlated and different inelastic processes may take place. The opposite case is the repulsive Bose gas where the pair inelastic process will be suppressed with increase in interaction. For completeness, in Fig. 6 we plot the relative momentum distribution obtained as the Fourier transform of R$_{2}$ ( r$_{ij}$ ) for various particle numbers for $^{87}$Rb condensate in the JILA trap, with a$_{s}$ = 0 . 00433 o.u. (100 a.u.). The width of the curve decreases and exhibits a sharp peak at k = 0, whose height increases with increasing number of particles. Lastly to visualize the effect of different strength parameter C$_{6}$ on the pair-correlation, we plot R$_{2}$ ( r$_{ij}$ ) against r$_{ij}$ for the previous sets of potential parameters in Fig. 7. We find 12 FIG. 5.
