The Ginzburg-Landau parameter $\\kappa=\\lambda/\\xi=30(6)$ ($\\lambda$ is the magnetic penetration depth, $\\xi$ is the coherence length) was estimated which is the highest among single element superconductors. The temperature dependence of the superconducting energy gap [$\\Delta(T)$] reconstructed from $\\lambda^{-2}(T)$ deviates from the weak-coupled BCS prediction.
