CERN ISOLDE 2015: Hyperfine Interactions in Pd foils during D/H electrochemical loading

  • As SKINR planned earlier in Current Science article, a physicist team linked to CERN made very interesting measurement on PdD/H loading, that may be key to PdD LENR understanding.
    They implanted some atoms in palladium, to probe some nuclear characteristic (Perturbed Angular Correlations). They found some spectrum common to H and D loading, but one spectrum is specific to D loading, and is elusive. They suspect it is a coherent distribution of D atoms around some probe atom. This spectrum is specific to deuterium loading and in only observed in some loading phase, looking like the elusive LENR phenomenon.
    Does it gives key directions ? Correlated states match prediction of many theories...

  • Research by Miley and Holmlid show that the hydrogen in microcavities in iron oxide is superconducting. Holmlid states that this Hydrogen Rydberg matter (aka metalized hydrogen) is a Bose condensate. The same must be true for the hydrogen clusters that form in highly loaded palladium.


    The root of this superconductivity is in the SPP EMF that covers the surface of these nanoparticles.


    In the Calanti wire experiments, as the LENR reaction begins to manifest, the electrical conductivity of the wire increases even as the heat production of the wire increases. The reason... the micro-cavities that cover the surface of the wire are filled with hydrogen Rydberg matter whose SPP surface is becoming more coherent (Bose condensation) as the LENR reaction sets in and is gaining strength.


    If a large magnetic field is applied to that wire, a pulse of x-rays will be produced as the Bose condensate is momentarily disrupted... try it.

  • Link with superconductivity are clear, like what the work of Paolo Tripodi have described.


    Note that at Avignon, Nicolas Armanet explained that beta-phase unlike alpha-phase was not diffused in the whole bulk, but progressing from a high density layer toward the inside.


    the PAC measurement anyway are extremely interesting as
    - they show an isotopic difference
    - they show the phenomenon is not always present


    this is not a simple phenomenon....
    Correlating that with some anomalous heat evidence would be great, but I imagine it is very hard.
    maybe with radiation which would be correlated with heat.
    However there is reason to expect that some radiations (neutrons) are anticorrelated with heat...


    food for researchers!

  • for those interestedn, here is a description of PAC method

    The technique of the perturbed angular correlation (PAC) belongs to the class of hyperfine spectroscopic methods as the Mößbauer-spectroscopy. The hyperfine interaction between the electromagnetic moments of the nuclear state and the external electromagnetic fields at nuclear site is measured. This technique can be used for determine the magnetic dipole and the electric quadrupole moments of the nuclear states and using nuclei with known moments for deriving the internal electromagnetic fields in solids, liquids, gases, ions and free atoms.


    So the perturbed angular correlation started with being a technique used in nuclear physics, measuring spins and parities. With the development of the experimental techniques the angular correlation was recognised having a high potential in condensed matter research and today its applications are predominantly in this area.


    The principle of perturbed angular correlation consists in producing a radioactive nuclei that decays over a γγ-cascade in the ground state of the daughter nucleus and to bring it into the host material under research. The initial state with nuclear spin |Ii, mi〉 decays (see figure 1) through the emission of a γ-quant γ1 in an interstitial state |Is, ms〉 and this under emission of a second γ-quant γ2 in the final state or ground state |If, mf〉.
