| Abstract: | Measurements of the transverse acoustic impedance of dilute solutions of 3He in superfluid 4He show that the fraction of 3He quasiparticles which are specularly reflected at a plane wall is temperature dependent between 0.1 and 1 K. Values of the 3He relaxation time are also obtained. |
