Note: Following binary elastic scattering, the kinetic energy of the primary or probe ions, \(E_{\rm{s}}\), is given by \(E_{\rm{s}} = E_{0}[M_{0}/(M_{0}+M_{1})]^{2} \{\cos\theta + [(M_{0}/M_{1})^{2} - \sin^{2}\theta]^{½}\}^{2}\) where \(E_{0}\) is the kinetic energy of the incident probe ion prior to scattering; \(M_{0}\) is the mass of the probe ion; \(M_{1}\) is the mass of the target atom; \(\theta\) is the angle between the initial and final velocity vectors for the probe ion, as determined from a common origin in the laboratory coordinate system, expressed as a value between \(\pu{0\!^{\circ}}\) and \(\pu{180\!^{\circ}}\).
