Abstract
The separated-oscillatory-field technique of subnatural-linewidth rf spectroscopy has been used to completely resolve the hyperfine structure of the state of hydrogen. The three-component resonance observed in zero magnetic field was fitted by a superposition of numerically obtained line profiles to determine the hyperfine spliting of the state. The result is 59.22(14) MHz.
