Abstract
The effect of nonlinearity on the change of shape of the surface of an unstable weak D-type ionization front is studied by the method of small perturbations. It is supposed that the gas ahead of and behind the front is incompressible. Expansion terms up to the second order inclusive are taken into account. It is shown that, in contrast with the deformation of a flame front and in the case of development of Rayleigh-Taylor instability, sections of the front with a large curvature are bulged not to the side of the less dense gas, but in the opposite direction.
