Tang—Toennies势计算低温氦的输运性质

CALCULATIONS OF TRANSPORT PROPERTIES OF HELIUM USING TANG-TOENNIES POTENTIAL AT LOW TEMPERATURE

本用Tang—Toennies势计算了0.1—100K温度范围内He^3,He^4和He^3—He^4系统在低密度下的输运性质,计算结果与Kestin等人拟合的数据吻合较好,说明Tang—Toennies势相当准确的描述了氮原子间的相互作用。

In this paper,Tang-Toennies potential is used to calculate the transportproperties of He3, He4 and He3-He4 at low density and low temperature(0.1 -100K). And the results be in better agreement with the data givenby Kestin et al. It is shown that the interaction between heliumatoms can be described quite perfectly by it.
