| Popis: | The second virial coefficient B for 84krypton (84Kr) vapor is evaluated over the broad temperature range 0.01–700 K. The classical expression for B, Bcl, as well as the first quantum correction Bqc and the Beth–Uhlenbeck formula for the quantum coefficient Bq, is used. The deviation from Bcl with decreasing temperature is marked out clearly. It turns out that B is a powerful indicator of the demarcation boundary between the classical and quantum regimes. The dependence of B on the input Kr–Kr potential is examined. In the high-T limit, it is found that B is weakly dependent on the type of potential. At lower T, the behavior of Bq reflects a remarkable degree the intimate details of the respective regions of the interatomic potential itself. The compressibility of the system is examined in both classical and quantum regimes. |
