The equations of state for a set of clusters Tin (n = 2–13) are derived using the method of scattered waves. The changeover from dimers to three-dimensional structures is considered a consequence of the sequential decrease in the degree of anharmon

The scattered-wave method is used to calculate the energy spectrum and wave functions of electrons in clusters of α-Ti and its alloys with B, C, and N. A clear asymmetry in the distribution of electron density is revealed, which distinguishes groups
