| 37 | // Class description: |
---|
| 38 | // This class is a container for cross sections and transport momenta |
---|
| 39 | // calculated by Penelope models (ionisation, bremsstrahlung). It stores |
---|
| 40 | // PhysicsTables/PhysicsVectors of |
---|
| 41 | // a) the "hard quantities" (above the threshold), 0-th order (cross section) |
---|
| 42 | // 1-st order (= stopping XS), 2-nd order (= straggling XS) |
---|
| 43 | // b) the "soft quantities" (below threshold), 0-th order (cross section) |
---|
| 44 | // 1-st order (= stopping XS), 2-nd order (= straggling XS) |
---|
| 45 | // c) total hard cross sections for individual oscillators |
---|
| 46 | // vs. energy. |
---|
| 47 | // |
---|
| 48 | // The interface *always* uses energy and cross sections, while internally |
---|
| 49 | // log(energy) and log(XS) are used. |
---|
| 50 | // |
---|
| 51 | // One instance per each cut-material couple should be created by the |
---|
| 52 | // calling class. |
---|
| 53 | // |
---|
| 54 | // Public method to retrieve hard cross section, soft stopping power, |
---|
| 55 | // total cross section and hard shell cross sections. |
---|
| 56 | // |
---|
| 57 | // The method NormalizeShellCrossSections() normalizes the |
---|
| 58 | // shell cross sections by retrieving the total hard cross section. |
---|
| 59 | // Used for sampling. |
---|
| 60 | // |
---|
| 61 | // Notice: all quantities stored here are *per molecule* |
