Development of JQMD (JAERI Quantum Molecular Dynamics) code

QMD(Quantum Molecular Dynamics) model has been proposed at the latter 80's and widely used to analyze various aspects of the heavy-ion reactions. We have developed the original QMD code (JQMD; JAERI QMD) in Advanced Science Research Center of JAERI and applied it not only to the heavy-ion reactions but also to the proton-induced reactions of the energy range from several 10 MeV up to 3 GeV per nucleon. Many important results obtained by using JQMD code, which have been already published in the several papers of nuclear physics and nuclear data, show that JQMD has its originality and good quality. In this report, we summarize physical models included in JQMD, explain the source code of JQMD, and describe the method to run JQMD in computers showing some examples. (author)
