Abstract

A photonuclear reaction transport model based on an isospin-dependent quantum molecular dynamics model (IQMD) is presented in the intermediate energy region, which is named as GiQMD in this study. Methodology to simulate the course of the photonuclear reaction within the IQMD frame is described to study the photo-absorption cross section and π meson production, and the simulation results are compared with some available experimental data as well as the Giessen Boltzmann–Uehling–Uhlenbeck model.
