having a sharper peak, as the net interaction increases. The peak at k = 0 becomes more pronounced with increase in effective repulsion, whereas for weak interaction it develops a long-range tail in the momentum space. The momentum is being redistributed to higher k values. The width of the low-momentum peak for a$_{s}$ = 0 . 00433 o.u. and A = 10000 is about 0 . 7 µ m − $^{1}$. 

We have remarked earlier that with recent progress in creating atomic clouds with large dipole moment, interest has been shifted to longer range interaction instead of taking only
