Energy dependence of resonant magnetic field. Measured resonance positions (abscissa) vs. collision energy (ordinate) as inferred from the zero-crossing of Δz CM for target clouds (blue circles) and projectile clouds (red squares). The zero-crossings were extracted from weighted curve fits of Δz CM using a pseudo-Voigt distribution (see “Methods” and Fig. 5). Horizontal error bars denote the 1σ-level confidence bound for fitted values of B res. Vertical error bars are the standard error for our calibrated collision energies. The solid line shows the theoretical prediction for the resonant position
