[2G12] Friction coefficient derived from time dependent density functional theory

*Takashi Nishikawa1, Yoritaka Iwata2,1, Satoshi Chiba1 (1. Tokyo institute of technology, 2. Shibaura Institute of Technology)

Keywords:friction coefficient, time dependent density functional theory, Langevin model

Langevin model can calculate the observable related to fission with high accuracy, but transport coefficient like friction tensor in Langevin equation has been calculated by static and macroscopic hydromechanical model. Friction means the energy exchange between macroscopic dynamics and internal nucleon degree of freedom, and Friction is important physical quantity which determine the number of emitted neutron and kinetic energy of fission fragment. In this study, We calculate friction coefficient of collision reaction by means of microscopic and dynamical framework theory, time dependent density functional theory and discuss the property.
