Enhanced effect of temporal variation of the fine-structure constant in diatomic molecules
- School of Physics, University of New South Wales, Sydney NSW 2052 (Australia)
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 cancellation between the hyperfine and rotational intervals.
