Experiments carried out at the ISKRA-5 facility
have demonstrated high (not worse than 3%) symmetry of
the X-ray radiation flux inside a spherical case (hohlraum).
This fact gave us an opportunity for investigating into
compression of the targets with the initial nonspherical
geometry. The asymmetry affects both the total neutron
yield and the moment of neutrons generation. In this paper
we present the simulation results of the asymmetric targets
dynamics which were carried out by means of the 2D MIMOZA-ND
code. This code allows to take into account effects of
nonstationary, nonequilibrium, spectral transfer of X-ray
radiation. Comparison between simulation results and experimental
data was made. It was demonstrated that one could observe
a satisfactory agreement between experimental data and
the total neutron yield, as well as the time delay of the
moment of neutrons generation.
