دراسة تطوح فقدان الطاقة للايون السريع مع الكترونات المادة مع الكترونات المادة

In the present work theoretical study carried out on the subject of energy loss straggling of fast Ion with matter electrons. There are many classical methods used to explanation of the energy loss straggling of fast ions. In this study we have used the method of Bohr of straggling process of the electron intruder collision on matter in which it calculated the cross section by using the effect impact-parameter. Comparison with the data obtained we have found a good agreement of range of the applied classical methods.
