Abstract
THE classical electron radius re is defined by e2/re = mec2. A sphere of constant density with radius re possesses a radius of gyration rg = (0.4)1/2re. The energy eigenvalues of the rigid rotator are not yet known in the extreme relativistic region ; but there one can quantize with integers k as for circularly polarized photons : thus rk/pk = kħ. For k = 1 and r1 = rg it can be deduced that: Thus the first rotation level compares with the first meson mass 212 me.
