Class Description

 JSFBeamGeneration

 Generate JLC beam momentum

$Id: JSFBeamGeneration.cxx,v 1.2 2003/02/04 01:18:33 miyamoto Exp $

 Using the input four random number, generate beam energy, eminus and eplus.
 Pointer to bases object is used to get additional random number
 xebm, xebp, xbsm, xbsp must be uniform random number between 0 to 1.

 Output energies, xeminus, xeplus are scaled energy [0,1+alpha]

 When both electron and positron have energy loss.

 When both electron and positron have energy loss.

 Create a data for beam generation.
