| Outline of Final Research Achievements |
During particle therapy, radionuclides are produced in patient bodies and equipment. As the nuclear reaction model, QMD (Quantum Molecular Dynamics) has been frequently used. On the other hand, AMD (Antisymmetrized Molecular Dynamics) has theoretical validity than QMD, although it is seldom adopted. In the present study, we investigate whether AMD can give accurate cross sections in particle simulation. As the result, we found that AMD gives comparable results with QMD in the most cases where experimental data exist. However, in the case of neutron production cross section of 12C+12C reaction, AMD is found to give better results. Therefore, we will make calculation database concentrating on neutron production cross section for light heavy-ions, which is necessary for neutron shield calculations.
