PSD is deduced from the Volterra integral equation of the first kind with the right part, which is by the dependence of Cherenkov radiation intensity (ChRI) from n, experimentally obtained for the given beam. PSD is the second derivative of ChRI. The problem of stability of the second derivative is solved by attracting the priori information (for example, nonnegative of the solution). Using optical dispersion of radiator is discussed. It enables to find PSD even in the single cluster of particles. The possibility of determining the PSD in the cross section beam is discussed too. The method also enables to find PSD upon a noticeable transverse speed of the particles in the beam. The method is virtually non-destructive in many cases.
