  The A - dependence of rho^0 meson production in neutrino-induced reactions is
investigated for the first time, using the data obtained with SKAT bubble
chamber. The nuclear medium influence on the rho^0 total yield and inclusive
distributions (on z = E_rho/nu and Feynman x_F variables) is found to be
approximately the same as for pions. It is shown, that these distributions,
with increasing A, tend to shift toward smaller values of z and x_F, thus
indicating on an increasing role of secondary intranuclear interactions. The
predictions of a simplified model incorporating the latter are found to be in
qualitative agreement with experimental data.
