摘要：

Recent experiments [1, 2] on the measurement of the spectrum of the Goldstone collective mode of a coherently precessing state in He-3-B are discussed using the presentation of the coherent-spin precession in terms of the Bose-Einstein condensation of magnons. The mass in the spectrum of the Goldstone boson-a phonon in the superfluid magnon liquid-is induced by the symmetry-breaking field, which is played by the RF magnetic field.
