// Class description:
|
|
// This class is a container for cross sections and transport momenta
|
|
// calculated by Penelope models (ionisation, bremsstrahlung). It stores
|
|
// PhysicsTables/PhysicsVectors of
|
|
// a) the "hard quantities" (above the threshold), 0-th order (cross section)
|
|
// 1-st order (= stopping XS), 2-nd order (= straggling XS)
|
|
// b) the "soft quantities" (below threshold), 0-th order (cross section)
|
|
// 1-st order (= stopping XS), 2-nd order (= straggling XS)
|
|
// c) total hard cross sections for individual oscillators
|
|
// vs. energy.
|
|
//
|
|
// The interface *always* uses energy and cross sections, while internally
|
|
// log(energy) and log(XS) are used.
|
|
//
|
|
// One instance per each cut-material couple should be created by the
|
|
// calling class.
|
|
//
|
|
// Public method to retrieve hard cross section, soft stopping power,
|
|
// total cross section and hard shell cross sections.
|
|
//
|
|
// The method NormalizeShellCrossSections() normalizes the
|
|
// shell cross sections by retrieving the total hard cross section.
|
|
// Used for sampling.
|
|
//
|
|
// Notice: all quantities stored here are *per molecule*
