For solids of several compositions, the archive contains numerical dependences of:

- differential probability per unit length
**d**of inelastic scattering of fast electrons (differential inverse inelastic mean free path) on the incident electron energy*W*(*E*,*Q*)/d*Q*and the energy loss*E*,*Q* - total probability
of the same scattering (total inverse mean free path) on the incident electron energy*W*(*E*),*E* - probability of scattering with energy loss under
(partial inverse inelastic mean free path)*Q*on the incident electron energy*R*(*E*,*q*)and the relative energy loss*E*,*q*=*Q/Q*_{max} - parameters for approximation of
(the inverse function to*q*(*E*,*R*)) on the incident electron energy*R*(*E*,*q*).*E*

For each specimen composition, the users are allowed:

- to draw and look through the graphs of
- dependences of differential probability
**d**on the energy loss*W*(*E*,*Q*)/d*Q*for chosen energy of incident electrons*Q*,*E* - energy dependences of the total probability
*W*(*E*) - dependences of scattering probability
with energy loss under*R*(*E*,*q*)for chosen energies of incident electrons*Q*on the relative energy loss*E*,*q*=*Q/Q*_{max} -dependences of inverse function*R*for choosen values of*q*(*E*,*R*), obtained both from the calculated values of*E***d**and with the help of approximation function;*W*(*E*,*Q*)/d*Q*

- dependences of differential probability
- to download the files containing
**d**,*W*(*E*,*Q*)/d*Q*,*W*(*E*)dependences and also parameters of the proposed approximation function.*R*(*E*,*q*)

The above-listed functions are described in General relations pages.
