✦ Synopsis

Using the path integration technique, developed by Brusov and Popov earlier for investigation of collective properties of superfluid phases of He 3 we study the collective mode spectrum in polar phase of He 3. This phase has points and lines of gap nodes. We derived equations, describing all 18 collective modes in this phase.The spectrum consits from Goldstone modes as well as from nonphonon ones, and all modes turn out three times degenerated.
