9. Due to the quadratic Zeeman effect, the (Formula presented) (Formula presented) sublevel is a weakly trapping state.
10. The coupling between Zeeman sublevels with (Formula presented) involves multiphoton transitions whose detuning δ from the intermediate Zeeman sublevels is of the order of the quadratic part of the Zeeman shift. For (Formula presented) it leads to an effective coupling of the order of (Formula presented) much smaller than C. For (Formula presented) the usual multiphotonic evaporation scheme works 1.

12. This effect should not be confused with the reduced efficiency of adiabatic following due to the many-sublevel structure pointed out in 10.
