Physics Lists A physics list is the mandatory user class making the general interface between the physics the user needs and the Geant4 kernel. It should include the list of particles The G4ProcessManager of each particle maintains a list of processes Geant4 provides several configurations of EM physics lists called

A new Geant4 physics list is prepared for nuclear physics applications in the domain dominated by spallation. The C++ translation of original Fortran INCL intra-nuclear cascade and ABLA fission/de-excitation codes are used in the physics list. The INCL model prepared is well established for targets heavier than Aluminium and projectile energies from 150 MeV up to 2.5 GeV - 3 GeV.

It is specified by the parameters described here. The Geant4 EM physics group recommends against setting EMRangeMin too low: Set to 100. eV or greater when using standard Geant4 EM physics. 2020-06-01 Using’Geant4’Validaon’to’Choose’Physics’Lists’ • UlGmately’you’mustchoose’aphysics’listbased’on’how’well’ its’componentprocesses’and’models’perform’ • physics’performance’ • CPU’performance’ • Geant4’provides’validaon’(comparison’to’data)’for’mostof’ physics_type ) const: Definition at line 337 of file G4VModularPhysicsList.cc.

Generated on Mon May 27 17:53:51 2013 for Geant4 by 1.4.7 2019-04-01 An example of the usage of this constructor in a physics list is given in the "dnaphysics" extended example, which explains how to extract basic information from Geant4-DNA Physics processes.

More simple solution is to use one of Reference Physics Lists provided in Geant4 Physics List library. Different approaches and variants of Physics Lists are shown in Geant4 novice, extended and advanced examples. • Geant4 physics list (FTFP_BERT) with step limiter • Started from novice/N02 example Example B3 • Schematic Positron Emitted Tomography system • Geometry with simple placements with rotation (G4PVPlacement) • Radioactive source • Scoring within Crystals via G4 scorers • Modular physics list built via builders provided in Geant4 2 Sep 2014 Does someone know what a Geant4 physics-list has to contain to perform a good neutrons' propagation from low to high energies (few keV to Geant4 Standard EM option 4 and Livermore Physics Lists are in good agreement with EGSnrc in the energy range 20–100 keV. •. We confirmed that breast You can use one of the GAMOS physics list, use one of the Geant4 physics lists or write your own one, following the standard Geant4 way, i.e. by writing your C++ The default list we provide is a Modular physics list.

These are the particles that Geant4 can track and therefore require processes to be assigned. Short-lived particles are not tracked, but they appear in some hadronic models, so a large list of resonances, quarks and diquarks is also defined.
