Proposed Stochastic Quantum Cascade Model(<Special Issue>Contribution to 21 Century Intelligent Technologies and Bioinformatics)

Abstract

We propose a new nuclear reaction simulation, termed the stochastic quantum cascade model, which deals with proton-nucleus elastic scattering and multiple inelastic reactions, for the purpose of more precise dose estimation in particle cancer therapy. Based on stochastic quantization theory, we describe the wave motion of protons using particle motion, i.e., Newtonian mechanics, and then incorporate elastic scattering into the framework of the intranuclear cascade model. Numerical calculations are carried out and compared with experimental angular distributions of cross sections. Reasonable agreements are demonstrated which verifies the high predictive ability and usefulness of the model.
