4 Introducing JAM (Jet AA Microscopic Transport Model) Y. Nara et.al. Phys. Rev. C61 (2000) 024901 JAM is a Hadronic Cascade Model, which explicitly treats all established hadronic states including resonances with explicit spin and isospin as well as their anti-particles. We have parameterized all Hadron-Hadron Cross Sections, based on Resonance Model and String Model by fitting the available experimental data.

8 New Feature (1) Event Generator Mode of P HI T S What are we doing in Monte Carlo calculations for particle transport ?  Solving one-body Boltzmann equation by using the evaluated nuclear data.  Simulating real phenomena by using event generators. MCNP type code PHITS for high energy by JAM, JQMD. energy is conserved in average. no correlations treat all ejectiles of collisions. energy and momentum are conserved in each collision. Only one-body observables Any observables Observables beyond one-body quantities are often required. Deposit energy distribution in a cell (pulse height tally). LET distribution in a micro dosimetry, Coincident experiments, ……… Event Generator

9 New Feature (2) Event Generator Mode for low energy neutrons in P HI T S We use the channel cross sections and neutron energy spectrum of the first neutron and assume the binary decay of recoiled nucleus. Neutron channels capture elastic (n,n’) (n,Nn’) charged particle and photon decay final state is uniquely determined charged particle and photon decay after the first neutron emission all particle and photon decay after the first neutron emission By this model, we can determine all ejectiles (neutrons, charged particles, nucleus and photons) with keeping energy and momentum conservation. PHITS can transport all charged particle and nucleus down to zero energy and estimate deposit energy without local approximation (kerma factor). Neutron data + Special Evaporation Model
