Measurements of the dead layer in superfluid 4He films on H3 and C60
We have measured the 2D 4He superfluid density, σs, on hydrogen and C60 using a high-Q Al oscillator, operated in an open geometry. We find that only 1 2 layer of helium remains normal well below the transition on hydrogen as opposed to 4 layers on the surface of bare C60. © 1994.
