The stability of a bounded plasma against the excitation of surface oscillations is considered when the electron velocity u(z) is inhomogeneous over the beam cross section. For surface waves with wave vector k/sub parallel/, a study is made of the resonance instability associated with the resonance point z/sub 0/, where K/sub parallel/u(z/sub 0/) =..omega../sub Le/+..omega../sub Le//root2, which is the sum of the frequency of the surface wave and the plasma wave. For sufficiently large gradients of the velocity u (z), the maximal growth rate is of the order of ..omega../sub Le/. (AIP)
