Nuclear and electronic coherence in superfluid helium

A semi-phenomenological model of a many-particle system 4He atoms is proposed, in which helium atom considered as complex consisting nucleus and bound pair electrons the singlet state. At zero temperature, there are two Bose-Einstein condensates particles with opposite charges, namely, condensate positively charged nuclei negatively electron pairs. It shown that such exist excitation branches: sound optical. On basis this an interpretation experiments on study eltctrical activity superfluid heliun proposed. The frequency at resonant absorption microwave radiation observed interpreted gap optical branch. distribution electric potential standing wave resonator similar to experimentally.
