• The dynamics of a coupled system between phonons and proton tunneling modeare investimated. Concernins nroton dvnamics, the C0CIgy decay processes to theheat bath, as well as the cour>Jinx mechanism to a t:>articular rhonon mode, aretaken into account in the seneralized-Lansevin ectuation describinz the coupleas>rstem. An exr>licit exr>ression of rhonon sr>ectral densit>r distribution in theenergy-rnornentum SPQCC IS derzved Wlthlll RPA 2PPU0X1012tl0n. Thus expressionseems to give an unified form which includes the various treatments hithertodiscussed as its extreme cases. Particularly a continuous cross-over behaviorfrom underdamped regime to the overdamped regime associated with protontunneling mode is discussed using the obtained unified expression.
