// G4 Model: Low energy elastic scattering with 4-momentum balance
|
|
// Derived fron G4LElastic of F.W. Jones, TRIUMF, 04-JUN-96
|
|
// Uses G4ElasticHadrNucleusHE and G4VQCrossSection
|
|
//
|
|
// Modified:
|
|
// 14-Dec-05 V.Ivanchenko rename the class
|
|
// 13-Apr-06 V.Ivanchenko move to coherent_elastic
|
|
// 25-Jul-06 V.Ivanchenko add 19 MeV low energy, below which S-wave is sampled
|
|
// 20-Oct-06 V.Ivanchenko default ekinhigh = GeV (use HE model)
|
|
// 16-Nov-06 V.Ivanchenko remove definition
|
|
// 16-Nov-06 V.Ivanchenko default ekinhigh = 0.4*GeV
|
|
// 16-Nov-06 V.Ivanchenko cleanup and rename Set methods and variables
|
|
// 28-Mar-07 V.Ivanchenko add NIST manager
|
|
// 11-May-07 V.Ivanchenko remove unused method Defs1
