Detailed Description

Cluster is a particle (inherits from the Particle class) that is actually a collection of elementary particles.

Definition at line 52 of file G4INCLCluster.hh.

Constructor & Destructor Documentation

G4INCL::Cluster::Cluster ( const G4int  Z, const G4int  A, const G4bool  createParticleSampler = true  )

inline

Standard Cluster constructor.

This constructor should mainly be used when constructing Nucleus or when constructing Clusters to be used as composite projectiles.

Definition at line 60 of file G4INCLCluster.hh.

                                                                                   :

void G4INCL::Cluster::boost ( const ThreeVector &  aBoostVector )

Boost the cluster with the indicated velocity.

The Cluster is boosted as a whole, just like any Particle object; moreover, the internal components (particles list) are also boosted, according to Alain Boudard's off-shell recipe.

Parameters

aBoostVector

the velocity to boost to [c]

void G4INCL::Cluster::freezeInternalMotion ( )

inline

Freeze the internal motion of the particles.

Each particle is assigned a frozen momentum four-vector determined by the collective cluster velocity. This is used for propagation, but not for dynamics. Normal propagation is restored by calling the Particle::thawPropagation() method, which should be done in InteractionAvatar::postInteraction.
