摘要：

The interplane spin cross relaxation time T-x measured by high frequency ESR in X-ray irradiated kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Cl is compared to the interplane resisitivity rho(perpendicular to) and the in-plane resistivity rho(parallel to) between 50 K and 250 K. The irradiation transforms the semiconductor behavior of the non-irradiated crystal into metallic. Irradiation decreases T-x, rho(perpendicular to) and rho(parallel to) but the ratio T-x/rho(parallel to) and rho(perpendicular to)/rho(parallel to) remain unchanged between 50 and 250 K. Models describing the unusual defect concentration dependence in kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Cl are discussed.
