WebResonant P-wave interactions can be described by a minimal zero-range model defined by a truncated effective range expansion, so that the only 2-body interaction parameters are the inverse scattering volume and the P-… 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

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).
