The impact parameter dependence of the disappearance of directed transverse flow has been investigated for {sup 40}Ar+{sup 45}Sc reactions using the Michigan State University 4{pi} Array upgraded with the High Rate Array (HRA). The energy at which collective transverse flow in the reaction plane disappears, the balance energy ({ital E}{sub bal}), is found to increase approximately linearly as a function of impact parameter. Comparison of our measured values of {ital E}{sub bal}({ital b}) shows agreement with predictions of Quantum Molecular Dynamics (QMD) model calculations. {copyright} {ital 1996 The American Physical Society.}
