Measurement of Roton Energies and Linewidths in He3-He4 Solutions
Abstract
Using Raman scattering from rotons in liquid He3-He4 solutions for He3 concentrations 0<=X<=0.11 at T=0.60 °K, we have measured the two-roton energy and linewidth. Our measurements indicate no change in the single-roton energy as a function of concentration, whereas the single-roton linewidth increases nonlinearly with X.
