The reduction in Rayleigh–Taylor instability growth rate because of density inhomogeneity in an incompressible ablatively accelerated plasma is calculated over a very wide range of physical parameters. In the low-wavenumber regime, the effect of the density gradient is to give a significant (about a factor of 2) reduction in growth rate as seen in fluid simulations.
