Energy dependence for directed and elliptic flow in intermediate-energy heavy ion collisions

Differential and integrated directed flow and elliptic flow of light charged particles （z ≤ 2） are studied systematically for semi-central （b = 5 fm） 197Au＋197Au collisions at incident energies from 25 to 250 MeV/nucleon by the isospin-dependent quantum molecular dynamics model. The changes of direc...

Description
Summary:Differential and integrated directed flow and elliptic flow of light charged particles （z ≤ 2） are studied systematically for semi-central （b = 5 fm） 197Au＋197Au collisions at incident energies from 25 to 250 MeV/nucleon by the isospin-dependent quantum molecular dynamics model. The changes of directed and elliptic flow with incident energy reflect the dynamic competition between mean field and nucleon-nucleon collisions and also between collective rotation and expansion.
