A calculation of the nuclear-spin lattice relaxation time T_1 in a superconductor containing resonance type impurities is presented. The Anderson model in a superconductor is adopted to describe the impurity in a metal and is solved in the Hartree-Fock approximation. The temperature dependence of T_1, calculated by the use of the non-magnetic solution, is compared with a recent experiment made on <Al>___-Mn alloys : Measured relaxation times deviate from the law of corresponding states which is thought to be valid for non-magnetic resonance states in the superconducting Anderson model. This comparison leads to the conclusion that there exists apparent spin fluctuation effects in <Al>___-Mn alloys.
