Consideration of the growth rate of the Rayleigh-Taylor instability at the decelerating shock front is made. The growth rate derived numerically by Murakami, Yabe and Niu has two characteristic features, i.e., (1) sharp decrease at some wavenumber and (2) existence of a flat part different from the formula √<gk>, where k and g are the wavenumber and the acceleration. The above (1) is explained by hydrodynamic flow behind the shock front. Confirmation of the existence of the constant term is the expression of the growth rate by Murakami et al. is made, but the phyical picture for this term is not clear yet.
