The cross-section dividing method and the simultaneous distribution between the deflection angle and the spatial displacement for charged particles penetrating through matters

Although Moliere theory is less accurate than Goudsmit-Saunderson theory due to the small angle approximation, there still remain many superior aspects of Moliere theory to the latter. Some problems are yet too difficult to solve through Goudsmit-Saunderon theory itself due to our mathematical insufficiencies and require Moliere and other results. Some Moliere results are still valuable in solving problems under Goudsmit-Saunderson theory. Some Moliere results will be useful in examining accuracy of the results derived through Goudsmit-Saunderson theory. We will look back and look forward again the significance of Moliere theory and Moliere results. (author)
