Developing a field independent frequency reference by averaging over transitions to multiple hyperfine levels
M. D. Barrett
We show that by averaging over transitions to multiple hyperfine levels, quadrupole shifts and dominant Zeeman effects exactly cancel whenever the nuclear spin, I, is at least as l…
