DESCRIPTION:Recently\, Raghavan has proposed an experiment to study neutri
 nos emitted and absorbed in recoil-free processes. We discuss the theory o
 f these "Mössbauer neutrinos"\, paying special attention to the oscillati
 on phenomenology. In particular\, we will show that\, in spite of the extr
 emely good energy resolution of the proposed experiment\, Mössbauer neutr
 inos can oscillate. After giving quantum mechanical arguments to support t
 his statement\, we will compute the oscillation probability of Mössbauer 
 neutrinos\, including localization and decoherence terms\, in a quantum me
 chanical wave packet model. We will then proceed to the calculation of the
  combined rate of Mössbauer neutrino emission\, propagation and absorptio
 n in the framework of quantum field theory. This approach allows us to avo
 id making any a priori assumptions on the neutrino wave function\, and it 
 can easily describe the various effects that broaden the neutrino emission
  and absorption lines. Finally\, we will also address the unrealistic\, bu
 t theoretically extremely interesting\, case of Mössbauer neutrinos affec
 ted only by natural line broadening and not by solid state effects.\n\nhtt
