WebJul 1, 2005 · It is predicted that the cross section for inelastic processes between 23Na and 133Cs and between 40K and 133C will be small as compared with the respective elastic cross sections. We present triplet and singlet scattering lengths for X--133Cs collisions (X=6,7Li, 23Na, 39,40,41K, and 85,87Rb). We consider the short-range potential-energy … Webfor which the Pauli exclusion principle prohibits s-wave in-teractions at all, at least for identical spin states. The rich variety of ultracold gases grows when we con-sider mixtures of different species. For instance, again in 87Rb, mixtures of the total spin states uf,m&5u2,1& and u1,21& have a positive mutual scattering length @2#, making
Webpotential.) For r > r0, the k = 0 wave function u0(r) will certainly approach a straight line of the form B(r − a), and it can be established that this a is indeed the scattering length. At this point, we see that the scattering length is defined by taking the large r form of the k = 0 wave function u0(r), and asking where
