    "abstract": "In order to increase the luminosity of electron-positron colliders it is\ndesirable to find a means to reduce the phase-space of the beams. The\ntransverse cooling of positrons imposed by the quantum excitation-free\nradiation emission in a single crystal is considered as a potential route to\nachieving ultra-cold beams. An analysis of the problem is presented, including\nan evaluation of the contribution from multiple scattering during the passage.\nThe analysis shows that an emittance reduction may be achieved in special\ncases, but in general the emittance will increase as a result of the multiple\nscattering.",
