Abstract

The off-resonant component of the radio frequency (RF) spectrum causes an ac Zeeman shift in the clock transition frequency. This shift has been measured for various detuning frequencies of the off-resonant field fed into the Ramsey cavity together with an interrogating probe field. This method directly measures the buildup of the frequency-dependent RF power within the cavity. We 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.
