1361- value of the member cpar has been changed back to the original
1362  value 1.5 in G4MultipleScattering.cc. The same is done in
1363  G4MultipleScatteringx.cc (the data member name is cparm there).
1364  This change affects all the results for low energy (< 1 MeV
1365  for electrons).
1366 
136715 may 01: L.Urban
1368- new multiple scattering version committed under the class name
1369  G4MultipleScatteringx. It gives better msc angle distribution
1370  than the standard G4MultipleScattering. It uses a distribution
1371  to simulate the geom./true pathlengths (standard : mean values
1372  only) and has a framework implemented in it to perform special
1373  stepping near to a boundary (this algorithm works, but some
1374  further development/tuning needed - this algorithm is disabled
1375  by default). This new version can be used after the change:
1376       G4MultipleScattering  --> G4MultipleScatteringx
1377  in the PhysicsList.
