We compute the energies of the bound state of an excited helium atom on the surface of liquid helium in a simple model. The consequent temperature dependence of the neutral current is in qualitative agreement with experiment. Studies of the neutral current in liquid helium, discovered by Surko and
Spectra of coupled electron-ripplon oscillation of two-dimensional (2D) Wigner crystal with the surface electron density n s =6.4Γ10 8 cm Γ2 (melting temperature of 0.58 K) are measured under conditions of both complete and noncomplete screening of the holding electric field in temperature range 0.0
