a Number of atoms N (circles) and b the Gaussian cloud width σz (circles) of the BEC after TOF for different values of the magnetic field B. The experimental results in a and b are overlayed by the calculated two-body loss-rate coefficient k2 (on a log scale) and scattering length a2,2, respectively (green lines). Each data point is the average of at least three measurements, and the error bars give the standard error.
