Abstract

The Homogeneously Precessing Domain (HPD) and the stationary state (Non-Precessing Domain, NPD) are particular cases of the more general states of the coherent Larmor precession in the3He-B. The symmetry is discussed between NPD and HPD which connects the properties of the dynamical HPD state with that of the conjugated stationary state of the3He-B. This symmetry allows us to obtain the spectrum of the NMR absorption due to excitation of the collective modes of Larmor precession, arising on the background of HPD.
