Simulation of Inelastic Neutron Scattering with GEANT4 — •Stephan Scholl, Michael Bauer, Josef Jochum, Marcel Kimmerle, Florian Ritter, and Klemens Rottler — Physikalisches Institut, Auf der Morgenstelle 14, 72076 Tübingen

An important background of direct dark matter search experiments consists of neutrons. Therefore the understanding and simulation of neutron–induced nuclear recoils is crucial to achieve an excellent sensitivity. Simulations of low-energy neutron scattering in GEANT4 show good agreement for elastic scattering but fail to reproduce the features of inelastic scattering. An improvement of the GEANT4 code is presented where the inelastic scattering is treated properly.
