Abstract:

A cell model of a Boson quantum system is described. The model has three phases at T 0 degrees K normal crystal, Bose condensed liquid, and Bose condensed crystal. The excitation spectrum for the Bose condensed crystal has two branches, a gapless vacancy wave mode and a vacancy-interstitial wave mode with a gap. It is proposed that the phase might be detected by neutron scattering in 4He near the liquid-solid transition line. Author
