Electronium (*e-) or (e- e+ e-) (mass 2.5 - 2.7 electron masses)a possible stable
bound state of the known Positronium Ion Ps- whose existence is most likely to be
proven shortly fills the bill for a "fractional orbit hydrino".
Ground state orbital velocity c/137.
Balanced orbital force = mv^2/r = kq^2/r^2 newtons
Ground state Potential V - kq/r =73.59 volts
For mass = 2.7 * electron mass r = 1.958e-11 meters
Most likely found in Argon-40 the by-product of Positron Decay of Potassium-40.
