Example matching potential sinks for the 27.2ev hydrino emission from the IAEA report are stated as
Pd2+/Li+, Ti2+, or K+/K+?.
The NIST data is approximate data for I.E s are
K+1/+2 = 31.6 eV
Ti+2/+3 = 27.4
I guess the molten silver gadget uses
Ag+2/Ag+3 = 34.8?
or Ag+1/Ag+2 21.8
I am not sure where Li comes in but there seem to be a good selection of metals that have IEs in the 27.4 area.
