"Magnetic" Mass of the Neutron — •Manfred Geilhaupt — HSN, Mönchengladbach, Germany

In Quantum Physics, the Spin of an elementary particle is defined to be an intrinsic, inherent property. The same to the magnetic moment (μ) due to the spin of charged particles - like Electron (me) and Proton (mp). So the intrinsic spin (S=1/2h-bar) of the electron entails a magnetic moment because of charge (e). However, a magnetic moment of a charged particle can also be generated by a circular motion (due to spin) of an electric charge (e), forming a current. Hence the orbital motion (of charge around a mass-nucleus) generates a magnetic moment by Ampère's law. This concept must lead to an alternative way calculating the neutrino mass (mν) while looking at the beta decay of a neutron into fragments: proton, electron, neutrino and corresponding kinetic energies. The change of neutrons magnetic moment (μn) during the decay process is a fact based on energy and spin and charge conservation, so should allow to calculate the restmass of the charge-less neutrino due to a significant change of: μe= -9.2847647043(28)E-24J/T down to μev= -9.2847592533(28)E-24J/T (while assuming mv=0.30eV to be absorbed and if (g-2)/2 from QED is independent of mass). As always the last word has the experiment
