 Abstract: CeCu2Si2 single crystals prepared with an excess of Cu exhibit low residual resistivity ρ0, low susceptibility χ, small unit-cell volume V, and bulk "heavy-fermion" superconductivity below 0.65 K, while crystals grown from stoichiometric melt show higher ρ0 and χ, larger V, but no superconductivity. CeCu2Si2 behaves as an s-state superconductor with strongly temperature-dependent pair breaking and almost isotropic Fermi surface.
