✦ Synopsis

Based on the reformulation of the Gor' kov equations by Eilenberger, Larkin, and Ovchinnikov, we propose a calculational method for transport coefficients in clean, type H superconductors. For the ultrasonic attenuation rate a (qllB) and the thermal conductivity K (VT _L B) we give analytical expressions near the upper critical field He2 at low temperatures. Comparison with experiment leads to satisfactory agreement with the theoretical results.
