概要

• 論文の詳細を見る

• Starting from Boltzmann-Langevin equation and performing a fluid dynamical reduction, a system of coupled Langevin equations is derived for a multipolar velocity field. This system is then applied to β-, γ-quadrupole resonances, making a link between microscopic approaches and phenomenological macroscopic ones. The validity of the markovian approximation made in the Boltzmann equation's collision term is discussed and some memory dependent two-body damping widths are calculated.
