13.2. List of physical processes that cannot be handled by PHITS

• Criticality calculation

• Interaction between two or more moving particles, for example simulation for particle collider experiments, and recombination of cations and electron.

• Effect of electric fields generated by radiation, for example laser acceleration of particles and plasma

• Electron-induced nuclear reactions

• Synchrotron radiation

• Nuclear elastic scattering of charged particles, except for protons and ions

• Charge exchange interactions [1]

• Polarization effect [2]

• Chemical reactions of materials but liquid water（e.g. Transport and generation of radicals）

• Change of chemical and material profiles after irradiation, for example time evolution of defects

• Delay of delayed neutrons (delayed neutrons are emitted promptly)

[1]

Feasible when the track-structure mode KURBUC is used

[2]

Feasible in the simulation of nuclear florescence resonance (NRF) and interaction between magnetic field and neutron spin.
