    "abstract": "For cutoff potentials, a condition which is not a limitation for the\ncalculation of physical systems, the S-matrix is meromorphic. We can express it\nin terms of its poles, and then calculate the quantum mechanical second virial\ncoefficient of a neutral gas.\n  Here, we take another look at this approach, and discuss the feasibility,\nattraction and problems of the method. Among concerns are the rate of\nconvergence of the \u0027pole\u0027 expansion and the physical significance of the\n\u0027higher\u0027 poles.",
