| Abstract: | We measured the mechanical response of nonsuperfluid 4He films adsorbed on a Ag substrate using the quartz-crystal microbalance technique. In 4He coverages from 0.06 to 0.1 atoms/Å2, we observed that the resonance frequency increases at low temperatures accompanied by a decease in Q-value. This behavior suggests that nonsuperfluid 4He films undergo partial slipping relative to the Ag substrate. |
