An extraordinary wave is excited in a plasma column with a long rf coil. The plasma absorption exhibits resonances for frequencies below the second ion gyroharmonic (..omega..<2..cap omega../sub i/). The resonances are shown to be similar, in the ion frequency range, to the Buchsbaum-Hasegawa resonances since they originate from a conversion at the lower hybrid layer of the electromagnetic wave into an ion Bernstein wave. Because of hot plasma effects, the short-wavelength converted wave is observed to propagate into the plasma core even for ..omega..>2..cap omega../sub i/. (AIP)
