The stationary spectra of current-driven ion-acoustic turbulence in a magnetized plasma (with the electron drift velocity v/sub d/ along B/sub 0/) are studied within the framework of quasilinear theory. In particular, a plasma with strongly magnetized electrons (..omega../sub c/e>kdv/sub T/e) and unmagnetized ions (..omega..>..omega../sub c/i) well above the threshold of instability (v/sub d//v/sub T/e>>v/sub s//v/sub T/e, ..nu../sub i/n/..omega../sub p/i) is considered. It is found that the waves are mainly excited in a narrow angular region almost perpendicular to v/sub d/ (i.e., cos thetaapprox. =v/sub s//v/sub d/<<1), which is in agreement with experimental results by Gekelman and Stenzel (Phys. Fluids 21, 2014 (1978)) and Batanov et al.
