Surface Tension of Liquid ^4He
Abstract
By measuring the oscillation frequencies of a levitated ^4He drop, we can determine the surface tension σ down to 0.4 K. The surface tension of ^4He was previously measured by several other groups. But there is 6% descrepansiy among their results. In this paper, we will report our recent measurement.
