Detailed Description

Coulomb distortion

Function Documentation

bringToSurface() [1/2]

IAvatarList G4INCL::CoulombDistortion::bringToSurface	(	Cluster *const	c,
		Nucleus *const	n )

Modify the momentum of an incoming cluster and position it on the surface of the target.

Same as the Particle-based bringToSurface method, but for incoming heavy ions.

This method returns a list of ParticleEntry avatars for the participant nucleons

Parameters

c	incoming heavy ion
n	distorting nucleus

Returns

a list of ParticleEntryAvatars

bringToSurface() [2/2]

ParticleEntryAvatar * G4INCL::CoulombDistortion::bringToSurface	(	Particle *	p,
		Nucleus *const	n )

Modify the momentum of an incoming particle and position it on the surface of the nucleus.

This method places Particle p on the surface of Nucleus n and modifies the direction of its momentum to be tangent to the Coulomb trajectory in that point.

The input particle has to be prepared with its asymptotic momentum. Its position is used only for the purpose of computing the asymptotic impact parameter; in other words, this method only uses the components of the position that are perpendicular to the momentum. The remaining component is not used, and can be set to any value.

This method returns a ParticleEntry avatar for the projectile.

Parameters

p	incoming particle
n	distorting nucleus

Returns

the ParticleEntryAvatar for the projectile particle
