This "faux n" is simply a Hydrino.
Well yes and no. As you have indicated on your site, it must be a hydrino of extreme shrinkage, such that it mimics a real neutron. IOW it must be able to get close enough to a target nucleus for the strong force to take effect - and presumably the great majority of hydrinos do not qualify.
[that is why the term faux-n is bit more elegant than having to explain this every time]
A valid question is the cross-section of the target nucleus for this hypothetical species.
If the faux-n has a significantly larger spatial near field - how does that change the cross section? The most logical answer would be to enhance.
In addition the faux-n will likely be highly energy deficient, having given up lots of EUV.
The net effect of both of these, taken together, is that the experimental situation tends to "hide the evidence" ...
...in that the faux-n is quickly adsorbed and with less likelihood of an immediate destabilization of the target nucleus- so there is less immediate induced radioactivity.
That scenario is both convenient as well as intuitive - of why there is so little evidence - especially in Pd - which has lots of isotopes which are stable with extra neutrons - so long as an immediate beta decay is avoided.
