Abstract

The quantum-mechanical Hamiltonian obtained by Ziman and by Thellung for an ideal liquid is diagonalized in the approximation of small compressibility. On taking account of the interaction terms between ‘phonon' and ‘roton’ variables, the roton rest energy is found to be proportional to the inverse of the sound velocity and to the ninth power of the wave number cut-off.
