Metzler: Observations of delocalized gamma emission from Co-57/Fe-57 samples during application of mechanical stress
Florian Metzler
Energy Production and Conversion Group, MIT Research Laboratory of Electronics
The research presented is motivated by a host of experimental reports where radiation is observed but not conventionally expected and others where radiation is not observed but conventionally expected.
Such reports raise questions about mechanisms for energy transfer into and out of atomic nuclei. Our group has pursued theoretical and experimental work to investigate the possibility of energy transfer into and out of atomic nuclei aided by the surrounding lattice.
Here, we report on a series of experiments designed to demonstrate lattice assisted transfer of nuclear excitation between nuclei. We refer to this mechanism as nuclear excitation transfer.
Such nuclear excitation transfer follows from models in which multi-level systems (nuclei) are coupled to shared oscillators (phonons) – analog to electronic excitation transfer today widely studied in biophysics. The transfer of energy from excited nuclei to nearby ground state nuclei implies subsequent gamma emission from different places. If such transfer is fast enough to take place repeatedly before radiative decay, macroscopic changes of the spatial distribution of gamma emission from a sample are expected.
We present data from recent experiments that suggest delocalization of gamma emission on the order of several hundred microns, induced by mechanical stress.
The experimental setup is as follows: Fe-57 nuclei in excited state (populated by beta-decaying Co-57) and Fe-57 nuclei in ground state are arranged on a steel plate; phonons are then generated in the steel plate via mechanical stress (in situ through thermal expansion of clamps). Correlated with such treatment we observe an increase of 14 keV gamma emission from plate regions with a high density of Fe-57 nuclei and a simultaneous decrease of 14 keV gamma emission from adjacent plate regions with a low density of Fe-57 nuclei.
Energy-resolved spatial data are obtained via an Amptek X123SDD detector which repeatedly raster scans across the sample via two precision linear stages. We interpret observed emission changes as effects of phonon-induced nuclear excitation transfer.
Specifically, we propose to explain the emission increase in some pixels of the raster scan and the commensurate emission decrease in adjacent pixels of the raster scan as resulting from net energy transfer into and out of those pixels. Such net energy transfer can be expected across the border of a low-density and a high-density region of Fe-57 nuclei, within the range of the transfer – which is consistent with reported observations.
As for the range of the transfer, we present early efforts to simulate the mechanism that match our results. The observed extent of delocalization of gamma emission is estimated to be on the order of 500 um.
For an individual transfer step of 10 nm (estimated from theoretical models) and with the assumption of a quantum walk pattern (as used in electronic excitation transfer studies), this suggests an average total number of 50,000 transfers before decay of the 14 keV state to ground state. With a 100 ns lifetime of the 14 keV state, this suggests a transfer step to take about 2 ps.
The new observations are consistent with earlier, preliminary results which will be summarized. Next steps and implications of these findings will be discussed.
Wonder Warthog is on vacation so I’ll be pinging the list for a couple weeks.

The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Such FReepers as Moonman62, TexasGator, CodeToad, Fireman15 and others who persist in polluting these threads have been asked to leave, and we are asking that they open their own threads if they have comments.
In June 2021, Wonder Warthog took over the Cold Fusion Ping List.

This topic has a following, people who wish to learn and discuss the materials presented.
Please refrain from posting anything that doesn’t legitimately address the issue.
Something is going on in this segment of science. There are a considerable number of research groups studying the matter.

[Vo]:Ferrous alloys and spin energy transfer - mostly overlooked in LENR
https://www.mail-archive.com/vortex-

There has been recent renewed interest in spin coupling in LENR as the m.o. of
energy transfer at the atomic level.
As it turns out – nickel is not optimum for the spin transfer process - while
iron is the best, but iron is not good for absorption of hydrogen.
In fact Tom Claytor could be several years ahead of the rest of the LENR world
in utilizing spin (and ferrous alloys) but he has been largely ignored since it
is assumed the ferromagnetic elements – iron nickel and cobalt would all
transfer spin energy in the same way - and nickel is a good proton absorber.
If John Wallace is on the right track, he may have provided a QM explanation
of why steel or an iron alloy can transfer spin energy more robustly than
nickel — but they are not optimum without alloying elements which allow high
loading. Iron is notorious for undergoing embrittlement, which is a type of
hydrogen absorption but possibly one which is destructive in the long run and
far from optimum without more…
… which brings to mind Claytor’s statement that the best alloy he has found for
LENR was a Mu metal alloy.
The use of Mu Metal as the active matrix for LENR could turn out to be the most
valuable detail relative to spin and LENR if Claytor is correct … using “
Co-Netic” as the matrix alloy. Mu-metal is a nickel-iron alloy, and the
proprietary alloy in question, Co-Netic - has high added molybdenum.

The high permeability makes mu-metal useful not only for shielding against
static and low-frequency magnetic fields but also in converting most of the
energy of an anomalous self-generated field into heat. This is a “soft”
magnetic material that saturates at low magnetic fields and that is the key to
the coupling magnons into heat. The high number of inherent Rydberg levels in
the ionization potential of this alloy could be the key. BTW – it should be
noted that Molybdenum is the closest Rydberg ionization fit to Mills theory of
all metals. That could be another key to understanding. No other metal is as
close to the precise value.

Wallace’s book can be ordered from his web site but it is not about LENR and is
highly technical.
What no one seems to be noticing is that this is about generating gamma rays just by inputting phonons, which is just VIBRATIONs.
Harnessing this would be like saying I got a spin-transfer railgun where I input a car battery and can fling a bb 5 miles and hit a moving car on its hood ornament at hypersonic speed.
