AbstractA compilation of data on the volume filling factor fv of the warm ionized medium (WIM) as a function of the local electron density ne indicates that approximately fv ∝ n−1e over 4 decades. This result is expected for a fractal ISM.

The YBa2Cu3-x(doped element)xO7-δ samples were prepared by solid-state reactions and studied by means of XRD, positron annihilation technique and simulation calculation. The results show the local electron density ne saturation and variations of oxygen content, which can be explained by the cluster effect. Another important new result is that the superconductivity does not depend directly on the valence electron density with different dopant. The Tc seems to lose the association with the ne variation. The dopants can be regarded as a kind of defects is similarly an adding or a losing oxygen ion. Oxygen interstitials reflect fractal distributions of dopants. The oxygen content and distribution reflect the superconductivity of the samples.
