摘要：
We consider the problem of stabilization of the Rayleigh-Taylor (RT) instability by the effects of the finite ion Larmor radius in a plasma with a curvilinear magnetic field. To this end, we use a kinetic description of flute waves generated by the RT instability with an arbitrary (with respect to the ion Larmor radius) wavelength. It is shown that disturbances with a characteristic scale of the order of the ion Larmor radius make a significant contribution to the instability increment and modify the well-known classic conditions for stabilization.
