Abstract
In the particle radiotherapy, it is necessary to understand behavior of atomic nuclei precisely in order to control the wave packets with a high degree of accuracy. In this work, we discuss wave packets dynamics in a system of two fermions by conducting computer simulation based on antisymmetrized molecular dynamics (AMD). In particular, We focus on nucleons as typical representatives of the fermions, which are components of atomic nucleus, and investigate time evolution in the process of two-nucleon scattering. As a summery, it turns out that the wave packets move regularly to escape Pauli forbidden region in phase space.
