Abstract
We have determined the scattering length of the a3Sigma+ potential of 87RbCs based on experimental observations from the literature and the known value for the long-range dispersion coefficient. Our analysis uses quantum defect theory and analytical solutions of the Schr\odinger equation for a van der Waals potential. We find that the scattering length is either 700^{+700}_{-300} a0 or 176\pm2 a0 with more confidence associated to the first value, where 1 a0=0.05292 nm is a Bohr radius. An independent value of the van der Waals coefficient could not be determined and the best theoretically determined C6 value was used.Citation
