Unexpected Mass Decoupling for 3He-4He Films on a Solid Hydrogen Substrate.
Quartz oscillator measurements reveal new behavior in 3He-4He mixture films on a H2 substrate. For mixture films of total coverage greater than one monolayer, in addition to the expected Kosterlitz-Thouless transition, a second mass decoupling event is observed, which behaves differently from the Kosterlitz-Thouless transition.
