This note opens up a new phase of ECE2 theory, beginning with the completely original theoretical demonstration that the vacuum produces electron spin resonance. By inference the vacuum produces nuclear magnetic resonance. So the properties of the vacuum can be explored in this way, through ESR in an electron beam and NMR in atoms and molecules. This would eb a precise and unequivocal demonstration that the vacuum produces resonance effects due to the the transfer of vacuum energy to material matter. The extra energy produced by the vacuum is the ESR resonance angular frequency multiplied by h bar. An experiment to detect this effect could be carried out by an adaptation of the well known Chambers experiment, where electron beams in a Young interferometer are affected by a magnetic field shielded from the beams, so only the potential is affected. The Young interferometer is replaced by a device to detect electron spin resonance. The Chambers experiment itself can be explained by the interaction of the vacuum vector potential with the electron beams. So I will now proceed to write up UFT336 parts one and two, in co authorship with Horst Eckardt as usual.
