- 論文の詳細を見る
The spectrum of rotons in superfluid solutions of He^3 and He^4 is studied theoretically in the dilute limit of He^3. We assume both the emission-absorption type and the scattering type interaction between rotons and He^3 quasi-particles and calculate the shift and the width of the roton energy at its minimum as well as the diffusion constant of He^3. The Raman scattering and the normal fluid density in the solutions are also studied. We then discuss the results of the measurements of the normal fluid density and of the Raman and the neutron scattering experiments on the basis of our analysis.
