论文摘要
仅具有排斥相互作用的软排斥模型的Uhlenbeck-Ford模型是通过包含吸引力扩展的。该扩展仍然允许对病毒系数进行分析评估。图形贡献的积分缩小为组合问题。我们已经计算了病毒系数的密度为6。该模型与更常见的相互作用之间建立了联系，例如12-6 Lennard-Jones的潜力。
The Uhlenbeck-Ford model for soft repulsion, which has only a repulsive interaction, is extended by inclusion of an attraction. This extension still allows an analytical evaluation of the virial coefficients. The integrals over the graph contributions are reduced to a combinatorial problem. We have calculated the virial coefficients to order 6 in the density. A link is made between this model and more common interactions, like the 12-6 Lennard-Jones potential.
