Fig. 4. The resonantly enhanced loss features observed by sweeping the magnetic field.(AtoE) The remaining molecule numbers are
plotted as a function of the magnetic field. The loss features provide clear evidence of the atom-molecule Feshbach resonances. The
resonance betweenj 0 ; 0 ; 3 = 2 ; 2 iandj 9 = 2 ; 7 = 2 iat about 101 G is also observed using this method. The solid red lines are phenomenological
Gaussian fits with reduced chi-square values of 1.2 (A), 0.81 (B), 0.66 (C), 1.4 (D), and 0.56 (E). The fits are not weighted to error bars. Each
data point represents the average of five to eight measurements, and the error bars represent 1 SD of the molecule number.
