“…These very small terms vary with energy in a way different to the strong nuclear interactions. If the latter are precisely known, the contributions of the neutron electron scattering [7,8] and the effect of the neutron's polarizability [9] can be separated from the total cross section in the range from zero energy up to some keV. The first analysis [9] of cross section data from the literature led to e,= 13_ 8; our own analysis of our data [10] resulted in e,=3+4.…”

Neutron transmission cross sections of lead and bismuth were measured for 143 keV and with high precision for 1970 eV neutrons which were selected from the reactor neutron spectrum by means of a novel dual combination of resonance scatterers. These data and highly accurate values of the coherent scattering lengths at zero energy and of transmission cross sections at 1.26, 5.19, 18.8 and 132 eV were the basis to determine the potential scattering radii, the neutron electron and the electric polarization scattering lengths as well as to test the used resonance corrections by which the influence of nuclear reactions on the results is eliminated. We obtained for the electric polarizability of the neutron: ~,=(0.8+1.0) 10-3fm 3 and for the neutron electron scattering length:b,e =(-1.32+ 0.04)i0-3 fm. In conclusion we have shown that these results favour the cloudy bag model for the description of the neutron's charge structure.

“…The exceptionally large electric fields associated with atoms and nuclei [91] 2 , make it possible for |β × E 0 |/c to exceed presently achievable external magnetic fields [92]. Such considerations yield significant limits on the neutron electric dipole moment [93], e.g., from neutron-noble gas scattering [91,94]. Returning to Eq.…”

Shedding light on dark matter: A Faraday rotation experiment to limit a dark magnetic moment

A Faraday rotation experiment can set limits on the magnetic moment of a electrically-neutral, dark-matter particle, and the limits increase in stringency as the candidate-particle mass decreases. Consequently, if we assume the dark-matter particle to be a thermal relic, our most stringent constraints emerge at the keV mass scale. We discuss how such an experiment could be realized and determine the limits on the magnetic moment as a function of mass which follow given demonstrated experimental capacities.

“…12,13 In these experiments, the strength of neutron-electron interaction was deduced from the interference between the neutron-nucleus and neutron-electron scattering. If the observed neutron-electron interaction strength is attributed entirely to the neutron EDM (d n ), an upper limit of d n ≤ 3 × 10 −18 e · cm is obtained.…”
