А calculation is reported of the mean charge $\bar{i}$ and the charge fractions $F_i$. of an equilibrium beam of helium ions in high and low density media as functions of the charge $Z_t$ of the target nuclei in the range $1\le Z_t \le 24$ and ion velocities in the range $V_0\le V\le 3V_0$. It is shown that the functions $\bar{i}(Z_t)$ and $F_i(Z_t)$ may bе very different in low and high density targets.
