The stopping power is generally normalized by the target scatterer density n, to produce the stopping cross-section, SCv). If one removes the primary velocity dependence and constants from the cross-section, one obtains the stopping number, L(y), where interesting physics is concentrated. These quantities are related as

The best-known example is for the first term in the expansion when the Bethe formulation is employed. In this case, the first, or Bethe-Bom term in Lq can be written, including the relativistic terms [3], as 

It is primarily with the various methods and approaches for calculating the stopping cross-section or properties related to it, as well as the various terms in the series expansion of the stopping cross-section that many of the chapters in this volume will be concerned.
