Bohr Theory,ReciproCity and Binary Stopping(Cross― Section

We have calculated the differential cross section spectra of electrons emitted in swift ion-atom collisions on the basis of classical Bohr theory for bare and dressed ions, the results are compared with the results of binary theory. Reciprocity may be utilized as a criterion to reject questionable experimental data. In cases where a certain stopping cross section hJs not been or cannot be measured, the stopping cross section for the inverted system may be available and serve as a first estimate The principle of reciprocity is to interchange of projectile and target ( z1 and zi) to find the effect of reciprocity on the differential cross section for dressed ions.
