Abstract
Torsional oscillator experiments with the submonolayer superfluid He-4 film on the porous glass have been performed in a rotating cryostat. A new additional dissipation peak was observed under the rotation. Thi s peak carl be interpreted as a result of the crossover from 2D to 3D nature of the superfluid state and formation of 3D-type vortices in th in He-4 film on porous substrate.
