AmBeGen.hh

// RAT::AmBeGen
// 10-Jan-2006 WGS
 
// Implements a GLG4Sim-style generator for the amBe reaction.  The class we use
// is AmBeSource, copied from the CfSource class by Vincent Fischer.
 
// To use this generator, the command is:
 
// /generator/add ambe POSITION[:TIME]
 
// (that is, the TIME is optional).  POSITION and TIME are the
// same as for the combo generator.  For example:
 
// /generator/add AmBe:fill
 
// Note that there is also no "defering" of any tracks of emitted
// particles into other events.  "TIME" refers to the t0 of the
// fission; the default is flat time distribution with a rate of 1 ns.
