The local electron density approximation is used to calculate the position and value of the maximum in the proton stopping cross‐section for gases and solids. The electron density of atoms in gases is calculated using the Hartree‐Fock‐Slater approximation. The electron density of solids is represented by a muffin‐tin model. The calculations show significant variations in the position of the stopping maximum as a function of Z 2 and demonstrate a substantial difference in the Z 2 ‐dependences for gases and solids. The calculation results are in qualitative agreement with experimental data.
