ICCF6 - x-ray, heat excess and 4He in the electrochemical confinement of deuterium in palladium

  • Hi,

    Recently Academia pushedn that ICCF6 article to me

    https://www.academia.edu/30642…of_deuterium_in_palladium


    It seems a reasonable experiment, that the author judge modestly as not definitive, with

    • excess heat
    • He4 measurement
    • X-ray film
    • correlation of He4 with Heat+Radiations energy


    The energy balance between heat excess and 4He in the gas phase has been found reasonably satisfied even if the low levels of 4He found do not give the necessary confidence to state definitely that we are dealing with the fusion of deuterons to give 4He. In the melted cathode, whose data are reported here, 4He was not found at the achieved sensitivity. X-ray film, positioned at 50 mm from the cell, roughly gave the image of the cathode through spots. The energy of the radiation and the total energy associated to it have been, respectively, evaluated as (89±1) keV and (12.0 ± 0.4) kJ. This value is ≈ 0.5% of the energy measured by calorimetry in the same interval of time.


    The experimental setup seems described in older papers

    How do you judge that paper?


    can we put it in perspective (expecially the X-Ray measurements) with recent theories...

  • Once more stop posting academia.edu sites.They try to fish people!

    You really don’t like Academia.edu!!! I Don’t use it much for the same reason that you state, and I think Researchgate is much better. That said, the paper Alain shared is indeed interesting, so I in this RG link you can read it without having to deal with Academia.edu.

    I certainly Hope to see LENR helping humans to blossom, and I'm here to help it happen.

  • Therefore, E = 89±1 keV was the estimate for one xray spot

    Cisbani et al said it might be related to Pd isotopes?

    "

    We believe that the radiation detected has to be searched among the stable isotopes of Pd

    or among its impurities having intense nuclear transitions close to the energy found. "


    a brief examination of livechart Pd gammas and for likely impurities.. Rh..Cd,,Ag..


    Ag109 has a metastable state at 88.0 eV with a halflife of ~40 seconds

    and Ag107 has has a metastable state at 93.1 eV with a halflife of ~44 seconds

    The average of 93 and 88 is of course 90.5

    Perhaps89±1 keV links with Biberian's Ag analysis of the F+P productive cathode in ICCF21.


    Nowadays there are much better methods of measuring gamma radiation
