Description
Collective flows from heavy-ion collisions have signals from the shapes of colliding nuclei. Most of nuclei are not spherical. The complex structures of atomic nuclei give various shapes: spherical, oblate, prolate shapes, and their co-existence. These shapes give different overlapped area of colliding heavy-ions. The emitting particles from the heavy-ion collision contain information of those nuclear matter which is formed at the colliding region. The transverse momenta of free nucleons are generated at this colliding region and they show collective phenomena. The directed flow (v1) depends on nuclear densities, and the elliptic flow (v2) comes from the eccentricity of overlapped shape. We study collective flows from heavy-ion collision with deformed nuclei. We simulate heavy-ion collisions at intermediate energies using Daejeon Boltzmann-Uehling-Uhlenbeck (DJBUU) model, and calculate the collective flows of free nucleons from collisions. Then, we discuss the effects of nuclear deformation, shape co-existence, and vibration in heavy-ion collisions.
