Enhanced effect of temporal variation of the fine-structure constant in diatomic molecules
Enhanced effect of temporal variation of the fine-structure constant in diatomic molecules
We show that the relative effect of variation of the fine-structure constant in microwave transitions between very close and narrow rotational-hyperfine levels may be enhanced 2--3 orders of magnitude in diatomic molecules with unpaired electrons like LaS, LaO, LuS, LuO, YbF, and similar molecular ions. The enhancement is result of …
