Abstract

We present torsional oscillator experiments on liquid3He with4He film on the sample cell wall. Our torsional oscillator has a thick sample space. To see the effect of the condition of scattering of3He quasiparticles at the wall,4He film was used as a surface boundary layer. The thickness of4He layer was 2.5 atomic layers to show the superfluidity. We compare the result with and without4He rich surface boundary layer.
