| Research Abstract |
We performed systematic studies of phenomena and various properties in excited nuclear many-body systems such as those in heavy-ion collisions, employing microscopic dynamical models. Antisymmetrized molecular dynamics (AMD) is mainly employed but useful information was obtained by comparisons with other models. We paid special attention to the effects of equation of state (in particular the symmetry energy in isospin-asymmetric systems) and the cluster correlations. In orderto describe the strong cluster correlations in heavy-ion collisions, we introduced a new theoretical extension into AMD, which enables calculations with much higher reliability.
