Abstract
The passage of 46-200 keV sodium ions through thin (≤15.2 μg/cm2) carbon layers has been simulated using the Monte-Carlo technique. The angular distributions agree very well with those obtained by Meyer1 in his theoretical work on plural and multiple scattering. The angular and thickness dependences of the nuclear stopping cross section are compared with the experimental results of Högberg.2 The agreement is good. Nuclear energy loss distributions are given for three acceptance angles of the detection system. The influence of the acceptance angle on the nuclear stopping cross section is also studied. For a small acceptance angle distributions at some scattering angles are given. A simple relation between the nuclear energy loss and the angular half width is found.
