|
||||

the form of theta0 is the same as in the Highland formula, but the
|
||||
parameter values are different for e+/e- and the other (heavy) particles;
|
||||
the change for the UseDistanseToBoundary case: tlimitmin = 10 stepmin;
|
||||
some cosmetics in ComputeTruePathLengthLimit.
|
||||
|

28 July 07: V.Ivant (emstand-V09-00-02)
|
||||
- G4eCoulombScatteringModel - updated screen radius model
|
||||

|
||||

|
||||
- G4UniversalFluctuation - added protection such that no sampling of
|
||||
fluctuations is done if mean energy loss at the step is below minimal
|
||||
excitation energy of the media. The fix is important for cases of
|
||||
low-dense gases and very small steps.
|
||||
|
||||
19 June 07: V.Ivant (emstand-V08-03-10)
|
||||

|
||||
step limitation by GeomFactor (L.Urban)
|
||||
|
||||
11 May 07: V.Ivant (emstand-V08-03-09)
|
