Abstract

We have used rf techniques and a fast hydrogen beam to observe in zero magnetic field the two-quantum transition

{}^{2}S_{\frac{1}{2}} \to {}^{2}D_{\frac{5}{2}}

in the

n = 3

state of atomic hydrogen. The possibility of using this and related transitions for a high-precision measurement of the fine-structure constant is discussed.
