Abstract :
The off-resonant component of the RF spectrum causes an AC Zeeman shift in the clock transition frequency. This shift has been measured by detuning an off-resonant sideband of a resonant RF field fed into the Ramsey cavity. This method directly measures the buildup of the frequency-dependent RF power within the cavity. The authors have calculated the detuning slope of the cavity resonance curve at the clock transition frequency. The value of the cavity pulling shift of KRISS-1 has been determined
