• Recently, superconductivity in PuCoGa_5 was discovered. It has the same crystal structure as CeMIn_5 (M = Ir, Co, Rh), which are often refered to as Ce-115's. The electron correlation in PuCoGa_5 is estimated to be weak compared with Ce-115's, and the filling number of electrons is considered to be far from 0.5/spin in the band which plays an important role in realizing the superconductivity. Nevertheless, the superconducting transition temperature T_c in PuCoGa_5 is almost by an order of magnitude higher than that in Ce-115's. In order to explain the superconductivity with high T_c, we adopt the periodic Anderson model and calculate T_c by solving the Dyson-Gor'kov equation derived by the third order perturbation theory with respect to U. By this calculation, we indicate that the superconducting state of PuCoGa_5 is a d-wave pairing state, and show that the good location of two Fermi surfaces results in the high T_c in PuCoGa_5.
