标题： A Microscopic Energy- and Density-Dependent Effective Interaction and its Test by Nucleus-Nucleus Scattering

摘要： 由Bonn势在核物质中计算出的有效核-核相互作用已被参数化为局部密度和能量相关的两体相互作用。 这使得可以计算原子核-原子核散射势的实部，并通过散射实验动态产生的密度范围（$\rho \leq 3\rho_0$）来检验这种有效相互作用。 将我们的计算结果与通过无模型限制分析方法从轻离子和重离子散射数据中提取的经验势进行比较，我们发现除了质子散射外，其余均存在定量一致性。 在这种情况下失败的原因可能归结于低密度下有效相互作用的性质，因为此时核物质的结果不够可靠。 高重叠密度下相互作用的成功证实了冷核物质具有软方程状态的经验证据。 显示英文摘要

摘要： An effective nucleon-nucleon interaction calculated in nuclear matter from the Bonn potential has been parametrized in terms of a local density- and energy-dependent two-body interaction. This allows to calculate the real part of the nucleus-nucleus scattering potential and to test this effective interaction over a wide region of densities ($\rho \leq 3\rho_0$) produced dynamically in scattering experiments. Comparing our calculations with empirical potentials extracted from data on light and heavy ion scattering by model-unrestricted analysis methods, we find quantitative agreement with the exception of proton scattering. The failure in this case may be traced back to the properties of the effective interaction at low densities, for which the nuclear matter results are not reliable. The success of the interaction at high overlap densities confirms the empirical evidence for a soft equation of state for cold nuclear matter.
