Electron screening is a traditional way to rationalise
the anomalous fusion results seen at low energy (<500 kev,, 100 kev )
bombardments of heavier atoms by protons etc
Lipinski.. Czerski Schenkel.. Lipson have all reported these results..
There may be some relevance to LENR reactions which appear to occur without bombardment.
Rosario Pizzone has a 2013 ppt.re
a NOT well funded or prolific field, which requires expensive time.. equipment.
maybe the best is yet to come from another field
Electron screening IMO cannot draw whole LENR picture, but it has many hidden secrets. With approaching the atom nuclei the electrons change from pin-point particles into an energetic continuum, which gets as nearly as dense, as the nuclear matter itself. We can see it for ionization energies of heavy atoms, where complete removal of first electrons takes just a few electronVolts of energy, but for removal of last electrons hundred kiloelectronvolts are already required. In many cases it requires gamma rays of such a high energy, that the fragmentation of nuclei occurs instead of removal last electrons from them. Frank Znidarsiac proposed a theory where electron orbital undulate in both transverse, both longitudinal waves, the mutual resonance of which can increase local energy density in such a way, most of electrons gets concentrated along connection line of atom nuclei. The mutual repulsive force of electrons would counteract the attractive force of protons up to high digree, so that the fusion would run smoothly.
Therefore the electron screening can be quite potent mechanism for explanation of LENR at the case of heavy atoms, which get activated by radiowave frequencies in TV and radiowave spectrum (compare Piantelli, Defkalion, Rossi etc experiments). For lightweight atoms like lithium not so much and for explanation of Lipinski fusion I proposed a different mechanism. Lipinski fusion apparently runs with mechanism, which doesn't rely on rare resonance condition, because it collides protons with lithium with over 60% efficiency.

This idea has it roots in stone age physics experiments. It's only based on measurements and first impressions of such that now sound like an explanation. If you shoot an electron at rigid mass it gets reflected by the orbital charge and deviated by the magnetic field that is dynamically created and also often given by the nuclear moment and of course the electron magnetic moment.
There is absolute no chance that such an electron impact will have any influence in a LENR reaction. The nuclear wave structure can only be manipulated by magnetic mass running on symmetric orbits to the inner waves. So far this can only be attained by H*/D* where the electrons synchronize with nuclear flux.
The idea that electrons as particles orbit e.g. a proton is an abstract picture (projection) that you can use to e.g. define a force balance. Any attempt to treat such an electron as e.g. a relativistic particle fails as the electron itself consists of magnetic flux (is at light speed already) that you cannot speed up as stone age physics believes. I checked all classic model including Mills one and all fail if you try to use a relativistic metric.
The correct orbit energies can only be gained if we use magnetic flux instead classic electron mass.
here is absolute no chance that such an electron impact will have any influence in a LENR reaction.
Vystoskii,Vysotsky and Bartalucci,2018
propose that Correlated Coherent States theory
explains the anomalous low energy fusion
(rather than electron screening )
and make predictions way down low
with impacts down to 1.5 kEV.
When and where?It might take years..
maybe Schenkel is interested?

A low energy ion irradiation facility, such as an ECR IonSource,
that can accelerate H+, D+, He+, and A+, is required.
Technical characteristics are a high current
(5 mA), low energy (100–1500 eV), ultrahigh vacuum
(UHV) (10−9–10−10 mbar), with one heating stage.
To provide accurate measurements, the contamination of the
target surface by even a few monatomic layers of carbon
and oxygen, where significant energy is deposited, is to be
avoided absolutely, and this can be done
by argon sputtering in a UHV environment (<10−10 mbar).
A LiF target will be irradiated with low energy H+ ions:
200 eV–1.5 keV
I would say that the Schenkel et al article quoted by both Berlinguette et all and by Ball, falls well into this category even if it’s called glow discharge.
Correlated Coherent States theory
explains the anomalous low energy fusion
The problem with such assumptions for regular grid structures is the irregularity in nuclear weights that lead to asymmetric coupling thus incoherence. This might work in a perfect lattice of a monatomic single isotope crystal.
In the case of the Hagelesteins /Metzler experiments the external force is dominant and the irregularities are a much smaller perturbation. But this only works in one direction given by the external force.
Conclusion: Correlated Coherent States in the large, as a general solution, do not work except when an external dominant force is at work.
In dense Hydrogen the situation is different and the ensemble is much smaller also the coupling force is much stronger.
