// ClassName: G4CRCoalescence ("CR" stands for "Cosmic Ray")
//
// Author: 2020 Alberto Ribon , based on code written by
// Diego Mauricio Gomez Coral for the GAPS Collaboration
//
// Description: This class can be optionally used in the method:
//
// G4TheoFSGenerator::ApplyYourself
//
// to coalesce pairs of proton-neutron and antiproton-antineutron
// into deuterons and antideuterons, respectively, from the list
// of secondaries produced by a string model.
// This class can be useful in particular for Cosmic Ray (CR)
// applications.
// By default, this class is not used.
// However, it can be enabled via the UI command:
//
// /process/had/enableCRCoalescence true
//
// It is assumed that the candidate proton-neutron and
// antiproton-antideuteron pairs originate from the same
// spatial position, so the condition for coalescence takes
// into account only their closeness in momentum space.
//
// This class is based entirely on code written by
// Diego Mauricio Gomez Coral for the GAPS Collaboration.
// The main application of this work is for cosmic ray physics.
//
// Notes:
// - In its current version, coalescence can occur only for
// proton projectile (because the coalescence parameters
// for deuteron and antideuteron are set to non-null values
// only for the case of proton projectile).
// - This class is not meant be used for secondaries produces
// by intranuclear cascade models - such as BERT, BIC and
// INCL - which should have already a coalescence phase.
//
// Modified:
