Abstract:

High resolution phonon reflection spectra from thin films of noble gases condensed onto a sapphire substrate at 2 K are presented. Phonon reflection signals from films of helium, neon, argon, krypton and xenon are found to be essentially identical, suggesting that quantum effects play no role. We argue, however, that the conventional interpretation of a change in the signal as due to heat escaping from the system cannot be valid for the solidified rare gases. Author
