电子结构计算的基础上，我们确定的超导电性的新型高温超导体PuCoGa 5的Pu 5f电子配对所造成的。假设离域Pu 5f状态，我们计算的理论晶体学常数非常接近的实验，和计算的比热系数比较合理的测量系数。理论上的费米面是准二维的，材料似乎接近磁相不稳定性。
On the basis of electronic structure calculations we identify the superconductivity in the novel, high-temperature superconductor PuCoGa5 to be caused by the pairing of Pu 5f electrons. Assuming delocalized Pu 5f states, we compute theoretical crystallographic constants very near to the experimental ones, and the calculated specific heat coefficient compares reasonably to the measured coefficient. The theoretical Fermi surface is quasi-two-dimensional and the material appears to be close to a magnetic phase instability.
