    Recent experiments [N. F. Declercq and E. Lamkanfi, Appl. Phys. Lett. 93, 2 (2008)] showed evidence of the relationship between the generation of leaky Rayleigh waves and the formation of the two reflected lobes and a null strip for bounded beam incidence at the Rayleigh angle. The evidence was...

    Abstract�� We observed a profile of nonequilibrium superfluid-normal (SN) interface of 4He near a vertical wall. A glass, brass or copper wall was used. The SN interface was produced by cooling liquid 4He in a bath from the bottom, where liquid 4He was pumped through a flow impedance...
