Query: Semiclassical study on Proton and Neutron   Starting from the existing semiclassical studies on hydrogenoid atoms, we
propose a similar intuitive exercise for the three-body quark systems
corresponding to protons and neutrons. In the frame of this toy model we try to
explain both the stabilities of proton and neutron with respect to the nuclear
interaction, and the spectrum of nucleonic resonances with J=1/2. Our choice is
motivated also by a good agreement obtained for the up and down quark rest
masses report. Taking into account the deterministic chaotic behavior of
many-body systems, the discussed exercise could be understood as an interesting
particular case of a quantum three-body problem which admits a semiclassical
treatment.
