Abstract

A separated-microwave-oscillatory-field technique has been used in conjunction with a fast atomic-hydrogen beam to measure the

2 {}^{2}P_{\frac{3}{2}} - 2 {}^{2}S_{\frac{1}{2}}

fine-structure interval in atomic hydrogen. The value obtained for the

2 {}^{2}P_{\frac{3}{2}} - 2 {}^{2}S_{\frac{1}{2}}

fine-structure interval is 9911.117(41) MHz.
