摘要：
A low-frequency, transverse electromagnetic wave is observed in a magnetized helicon plasma with 1 >beta >nu(e)/Omega(e). The wave is localized to the vicinity of the largest plasma density gradient and appears only at a low neutral pressure. Based on the scaling of the wave frequency and amplitude with magnetic field strength, the wave is identified as the resistive drift Alfven wave.
