Studies of two-dimensional electron gas on the surface of liquid                helium, and three-dimensional solid helium-four, focussing on                   evidence for quantum tunnelling of electrons or helium atoms.                   The solid helium-four study will be conducted using ultrasonic                  attenuation, thermal conductivity, heat capacity and heat pulse                 propagation experiments to look for quasiparticle excitations,                  defect behavior, and evidence for the formation of a                            "supersolid"-- the solid state analogue of a superfluid.                        Measurements of the escape rate of electrons from the surface of                liquid helium will be performed in order to characterize the                    groundstate and excitations of the two-dimensional electron                     system.
