Content and use
For solids of several compositions, the archive contains
numerical dependences of:
- differential probability per unit length
of inelastic scattering of fast electrons
(differential inverse inelastic mean free path)
on the incident electron
energy E and the energy loss Q,
- total probability
of the same scattering (total inverse mean free path)
on the incident electron energy E,
- probability of scattering with energy loss under
(partial inverse inelastic mean free path)
on the incident electron energy E
and the relative energy loss
q = Q/Qmax,
- parameters for approximation of
q(E, R) (the inverse function to
on the incident electron energy E.
For each specimen composition, the users are allowed:
- to draw and look through the graphs of
- dependences of differential probability
on the energy loss Q
for chosen energy of incident electrons
- energy dependences of the total probability
- dependences of scattering probability
with energy loss under
for chosen energies of incident electrons E
on the relative energy loss
q = Q/Qmax,
- R-dependences of inverse function
for choosen values of E, obtained both from the calculated values
of dW(E, Q)/dQ
with the help of approximation function;
- to download the files containing
R(E, q) dependences and also
parameters of the proposed approximation function.
The above-listed functions are described in
General relations pages.
To get the data, open Data page
and choose a material composition you are
interested in by clicking at corresponding cell of the table in the top frame.
The chemical name of the chosen material will appear in the
relevant small window.
Use the commands from the tables in the bottom frame for choosing the
E values, drawing and viewing graphs, and downloading files:
- Add the curve to command strings create a new graph or append
an existing graph with additional curve.
- Show or Clear command strings open or clear the
windows with accumulated graphs.
- Command strings File *.pl download the appropriate files.
The structure of downloaded files is described in the
Data files page.
