Proposed StochasticQuantumCascade Model

PVb prqpose a new nuclear reaction simulation, tenned the stochtzytic quantum cascade modeL which deals with proton-nucleus elastic scattering and multiple inelastic reactions. for the purpose qfmore precise dose estimation in particle cancer therapy. Based on stochastic guantization theor},, we describe the wave motion ofprotons using particie motion, i.e., IVbwtonian mechanics, and then incorporate eldstic scattering into the17'amework ofthe intranuclear cascade modeL IVtimerical caiculations are carried out and compared with experimental angular distributions of cross sections. Reasonabie agreements are demonstrated which verij}es the high predictive ability and usojiilness ofthe moclel.
