摘要: We present discussions about the value of the transport coupling constant lambda(tr) in YBa2Cu3Oy. We have also reanalyzed our previous impurity scattering data according to the recently suggested relation between the momentum-dependent anisotropic function f(k), the ratio of anisotropic to isotropic scattering g(I), and the normalized order parameter e(k). Using the appropriate values of the transport properties and the plasma frequency, it is found that lambda(tr) as low as 0.2 is still a plausible value. Furthermore, we have studied the case of [ef](2)=0.81, which corresponds to f(k)=+/-1. For lambda(tr)=0.2, g(I)=0.67 for in-plane oxygen defects and g(I)=0 for Zn impurities, respectively. If lambda(tr)=0.3, g(I)=0.82 for in-plane oxygen defects and g(I)=0.33 for Zn impurities, respectively.
