In a hydrogen plasma (T/sub e/=2.5 eV, T/sub i/=1.5 eV), excitation of ion Bernstein waves by an externally placed electrostatic antenna has been investigated for ..omega..approx. =2..cap omega../sub i/. Mode transformation of the electron plasma wave at ..omega..approx. =..omega../sub p/i without observable reflection was observed, followed by strong excitation of the ion Bernstein wave. Detailed measurements of k/sub perpendicular/(..omega..,kparallel) and of the wave-packet trajectory show excellent agreement with theory.
