Note on Electron-Neutron Interaction

  • Edward U. Condon


Assuming a possible short-range interaction between electrons and neutrons of the form V = (r N - r e ) where δ is the Dirac delta function and r N and r e are the vector positions of electron and neutron, respectively, it is shown that probably |K| < 30mc 2(e 2 /mc 2)3 from consideration of the effect of the interaction on slow neutron scattering cross sections. If K is positive and a little less than this upper limit this interaction could be responsible for the observed isotope displacement or spectral energy levels.

    This idea that the zero-point oscillations of the hydrogen in a molecule may affect the slowing of neutrons by matter was suggested by Professor Rabi in a conversation last fall. See also Halban and Preiswerk, Nature 136, 951 (1935) for experimental indications of such an effect.ADSCrossRefGoogle Scholar
