Phys. Rev. Lett. 100, 133202 (2008) [4 pages]Collisional Control of Ground State Polar Molecules and Universal Dipolar ScatteringReceived 29 November 2007; published 4 April 2008 We explore the impact of the short-range interaction on the scattering of ground state polar molecules and study the transition from a weak to strong dipolar scattering over an experimentally reasonable range of energies and electric field values. In the strong dipolar limit, the scattering scales with respect to a dimensionless quantity defined by mass, induced dipole moment, and collision energy. The scaling has implications for all quantum mechanical dipolar scattering. Furthermore the universal scattering regime will readily be achieved with polar molecules at ultracold temperatures. © 2008 The American Physical Society URL:
