Abstract
The angular dependence of the resistivity rho(theta) has been measured in the superconducting transition region in (Tl-2/3,Bi-1/3)Sr2CaCu2Ox crystals. This resistivity has been successfully scaled using an anis otropic effective mass model with an anisotropy gamma = (m(c)/m(ab))(1 /2) of 9-12, which is larger than in YBa2Cu3O7, but much smaller than in Bi-2212 or Tl-2212 compounds. This study was performed for measurem ents with the current applied along the ab planes or along the c axis.
