**EXAMPLE:**

Energetic nuclear recoil probability for Electrons in Silicon with Exponential form factor and E

_{ener}=0.1 MeV:

**NOTE:**

_{ener}value is derived by

**(probability in cm**.

^{2}g) x (absorber density in g cm^{-3}) x (traversed thickness in cm)E

_{ener}is the the lower limit of recoil energy (for explanation see Energetic Nuclear Recoil Page)

^{2}/g is obtained as a weighted sum in which each material contributes proportionally to the fraction of its atomic weight. An example for selection, with water (H

_{2}O) as target, follows:

or equivalently

However the transferred energy is several order of magnitude larger at high scattering angles.

The overall results is that the NIEL and the Nuclear Stopping power (thus, the Recoil Probability) are affected by the form factor. Numerical results for 183 MeV electrons in In are presented in the following table:
