Abstract
We have investigated the elastic properties of polycrystalline neon films w hich were quench-condensed on a high-e silicon double-paddle oscillator. On annealing the sound velocity of the neon film was found to decrease irreve rsibly. The internal friction could be significantly reduced by annealing. It showed at all annealing stages only little variation with temperature be tween 40 mK and 2 K but increased very strongly above 3 K. (C) 2000 Elsevie r Science B.V. All rights reserved.
