Detailed Description

The Nucleon class represents a nucleon in a nucleus. It has an id number (proton or neutron) an impact parameter position (absolute and relative to the nucleus center), a status and a state to be defined and used by a SubCollisionModel.

Member Enumeration Documentation

enum Status : int

Enum for specifying the status of a nucleon.

Enumerator
ELASTIC	The nucleon is not wounded.
DIFF	The nucleon is elastically scattered.
ABS	The nucleon is diffractively wounded.

Constructor & Destructor Documentation

Nucleon ( int  idIn = 0, int  indexIn = 0, const Vec4 &  pos = Vec4()  )

inline

The constuctor takes a particle id and a position in impact parameter relative to the nucleus center as arguments.
