Leif Holmlid sites J. E. Hirsch when he describes metallic hydrogen as a superconductor. Holmlid et al have verified that the hydrogen trapped in the microcavities present in iron oxide are superconductors. Hirsch now believes that all superconductivity in high Tc cuprates as well as all other superconductors are hole superconductors.

(Color online) Cluster with more than 100 hydrogen atoms squeezed in palladium crystal defect with superconducting properties measured by SQUIDS (Lipson et al. , 2005; Miley et al. , 2007) is generated, see Figure 1 in Miley et al. (2008).] The detection by MFMP of the x-ray burst is experimental evidence that hole superconductivity is present at temperatures near 1000C. The detection of this radiation burst can be cited as verification of the existence of high temperature superconductivity produce by a hole superconductor as cited by Holmlid. This bremsstrahlung like radiation has no K line spikes that always appears in this continuum. The characteristic x-ray emission which is shown as two sharp peaks in the illustration at left occur when vacancies are produced in the n=1 or K-shell of the atom and electrons drop down from above to fill the gap. The x-rays produced by transitions from the n=2 to n=1 levels are called K-alpha x-rays, and those for the n=3→1 transition are called K-beta x-rays. http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/xrayc.html The lack of these K line spikes indicate that the bremsstrahlung like radiation was generated by something other than an interaction of high energy electrons impacting on a metal lattice.
