Charge-exchange control. a Charge-exchange rate for different initial hyperfine states of Rb atoms. b Density dependence of the charge-exchange rate averaged for \(\left| {1,0} \right\rangle _{{\mathrm{Rb}}}\) and \(\left| {1, - 1} \right\rangle _{{\mathrm{Rb}}}\). From a fit to a power-law we estimate the charge-exchange scaling on the density to be k_CE ∝ ρ^0.94(8). Error bars represent 1 SD
