Fig. 4: Atom-loss and temperature measurements for non-condensed samples in state (3, 2).

a, c Normalized number of remaining atoms N and b, d temperature T for varying hold time t in the region around 160 G (40 G). For a and b, the scattering length a2,2 is set to 88 a0 (circles), 274 a0 (squares), 379 a0 (diamonds), 452 a0 (triangles), and 517 a0 (crosses) for B = 151.1 G, 160.3 G, 167.0 G, 172.4 G, and 177.7 G, respectively. The inset in b) shows the measured temperature for the sweet spot with a2,2 = 274 a0. For c and d a2,2 is set to 89 a0 (circles), 247 a0 (squares), 377 a0 (diamonds), 449 a0 (triangles), and 517 a0 (crosses) for B = 37.1 G, 40.7 G, 43.7 G, 45.4 G and 47.0 G, respectively. Each data point is equal to the mean of three to five repeats, and the error bars reflect the standard error. The solid lines fit the data as discussed in the main text. The loss-rate coefficients obtained from the fits are given in Table 1.
