The energy at which the collective transverse flow in the reaction plane disappears, the balance energy Ebal, is found to increase linearly as a function of impact parameter for 40Ar+45Sc reactions. Comparison of our measured values of Ebal(b) with predictions from quantum molecular dynamics (QMD) model calculations agrees better with an approach incorporating momentum dependence in the nuclear mean field. © 1996 The American Physical Society.
