Abstract：
The collective matter flow in the ⁶⁴Zn- ²⁷Al reaction at 57MeV/u is measured in terms of a 4πcharged particle array. The events as a function of the impact parameter are sorted by using the average parallel velocity method. The reaction plane is determined by means of the transverse momentum analysis method. It is observed that the collective transverse momentum in the reaction plane (sideward flow parameter) varys with the impact parameter and producted particles.
