Scattering mechanisms of a c-axis aligned (Bi, Pb)_2Sr_2Ca_2Cu_3O_y have been studied by a numerical analysis based on a model in which two scattering mechanisms, phonon-electron scattering and electron-electron scattering , are coexisting as the main cause of the thermal conductivity enhancement below the superconducting transition temperature, T_c. We found a fairly good agreement between experimental results of temperature dependence and magnetic field dependence of the thermal conductivity and the coexisting model, as well as the model with electron-electron scattering (Proc. US-Japan WS on J_c in high T_c Oxide Superconductors (Oct. 1995, Tsukuba) : to be published), suggesting the coexistence of above mentioned two scattering mechanisms.thermal conductivityBPSCCOscattering mechanismBRT theoryquasiparticle damping
