Abstract:
We can pump magnons to a nearly harmonic magneto-textural trap in superfluid $^3$He–B. Using the NMR spectroscopy of levels in the trap we have measured the anisotropic magnon mass and related values of the spin-wave velocities. Based on our measurements we provide values of the Fermi-liquid parameter $F^a_1$.
