| Popis: | The second virial coefficient B for 132xenon (132Xe) vapor is evaluated over the broad temperature-range 0.1 mK–30 000 K. The classical expression for B, B cl, is used, as well as the first quantum correction B qc, and the quantum second virial coefficient, B q. The borderline interfacing the classical and quantum regimes is explored. It turns out that B is a powerful indicator of the demarcation boundary between the classical and quantum regimes. Equally important is that a very large negative B q is symptomatic of conditions favoring clustering. Small 132Xe clusters are predicted at low temperatures ~10−2 K. Our results are compared to previous results whenever possible. The agreement is very good. |
