摘要：

We have studied the free expansion of a Bose condensate in which both the usual s-wave contact interaction and the dipole-dipole interaction contribute considerably to the total interaction energy. We calculate corrections due to dipolar forces to the. expansion of such a condensate after release from a trap. In the Thomas-Fermi limit, we find that the modifications of the shape of the expanding condensate are independent of the total number of atoms.
