Abstract :
The Rayleigh-Taylor(R-T) Instability is one of the problems in the Light-Ion-Beam(LIB) Inertial-Confinement-Fusion (ICF)-pellet. The nonuniform acceleration field and the radiation effects on the LIB-ICF-pellet implosion to the high density are investigated by the linear analyses in this paper. By means of these analyses we obtained the following two results: 1) The nonuniform acceleration field in space does not change the growth rate(γ) of the R-T instability. However this nonuniformity may suppress the R-T instability in some particular cases. 2) The radiation may reduce the growth rate(γ).
