测量了液氪和氙气的声速，测量精度为0.1%，测量压力在蒸汽压和约65atm之间，从它们的三点处到临界点附近。对这些测量结果和以前在Ar中的结果进行的对应状态处理表明，在适当选择相对分子参数(σ，e)时，W*(P*，T*)表面除了Ar在临界温度附近外，其他表面都在实验误差范围内。从这种分析得到的有效原子半径σ的相对值比从其他热力学性质得到的值略低。
The velocity of sound was measured with a precision of 0.1% in liquid krypton and xenon at pressures between the vapor pressure and about 65 atm, from near their triple points to near their critical points.A corresponding states treatment of these measurements and previous results in argon showed that, with a suitable choice of relative molecular parameters (σ,e), the W*(P*,T*) surfaces were coincident to within the experimental error, except for argon near the critical temperature.The relative values of the effective atomic radii σ obtained from this analysis were somewhat lower than those obtained from other thermodynamic properties.
