Microwave shielding of ultracold polar molecules on the transition n=1->2 [dataset] Open Access

We show that microwave shielding on the rotational transition n=1->2 can be effective in preventing destructive collisions between ultracold polar molecules. It is slightly less efficient than shielding on the transition 0->1, but has some important advantages. In particular, it does not produce 2-molecule bound states under the conditions needed for shielding, so it will not enhance 3-body recombination. It thus obviates the need for double-field microwave shielding using a second field of different polarization.
