The calculations that model this process are relatively simple, assuming projectile energy is in the range corresponding to Rutherford scattering. Projectile energy range for light incident ions is in 0.5-3.0 MeV range. For heavier projectile ions such as 127I the energy range is usually between 60-120 MeV; and for medium heavy ion beams,36Cl is a common ion beam used with an energy of approximately 30 MeV. For the instrumentation section, the focus will be on heavy ion bombardment. The "E2" transferred by projectile ions of mass "m1" and energy "E1" to sample atoms of mass "m2" recoiling at an angle "ϕ", with respect to the incidence direction is given by the following equation.
