// It is the implementation of the NEW UNIFIED ENERGY LOSS PROCESS.
|
|
// It calculates the continuous energy loss for muons.
|
|
// Processes giving contribution to the continuous loss :
|
|
// ionisation (= cont.ion.loss + delta ray production)
|
|
// bremsstrahlung
|
|
// e+e- pair production
|
|
// can be added more easily ..........
|
|
// This class creates static muplus/muminus dE/dx and range tables ,
|
|
// which tables can be used by other processes.
|
|
// ************************************************************
