Recent developments in the point wise neutron treatment for FLUKA v4

The present paper describes the new, original implementation of a point-wise neutron treatment that is made available with FLUKA v4.3-0 ( https://fluka.cern ). development based on pre-processed data libraries for Geant4 code https://cern.ch/geant4 was written from scratch in C++ and able to load information all databases (ENDF, JEFF, JENDL, CENDL, BROND), including materials S(α,β,T) nuclear binding effects. It can perform online Doppler broadening at any temperature defined by user. carries out interactions fully correlated way, conserving quantities like energy momentum exception S(α,β,T). Special attention has been given minimize CPU penalty, which typically associated interactions.
