Abstract

The impact parameter dependence of the disappearance of directed transverse flow has been investigated for ⁴⁰Ar+⁴⁵Sc reactions using the Michigan State University 4π Array upgraded with the High Rate Array (HRA). The energy at which collective transverse flow in the reaction plane disappears, the balance energy (E_bal), is found to increase approximately linearly as a function of impact parameter. Comparison of our measured values of E_bal(b) shows agreement with predictions of Quantum Molecular Dynamics (QMD) model calculations.
