Abstract

Quantum beats have been observed in both linear- and circular-polarized light using a beam-tilted-foil geometry for the

3 s {}^{3}S - 3 p {}^{3}P

transition of

{}^{14}N

iv. Beats between the

F = 0

and

F = 1

hyperfine levels—forbidden in the case of excitation by untilted foils—were observed. A value of

A = 695 \pm 15

MHz was obtained for the hyperfine coupling constant of the upper term.
