Polarizability of the neutron

1990

Abstract A first measurement of quasi-free Compton scattering by the neutron bound in the deuteron has yielded a value for the polarizability of the neutron of αn=(11.7 −11.7+4.3)×10 −4fm 3. This means that a finite value for the polarizability has been obtained, though the result is still consistent with zero. The π0 decay constant Fπ 0γγ and the pion nucleon coupling constant gNNπ have opposite signs.

Electromagnetic polarizabilities of nucleons bound in 12C and 16O

1992

Abstract The polarizabilities of nucleons imbedded in 12C and 16O nuclei are measured via Compton scattering of 61 and 77 MeV photons, leading to α N = (11.5±0.8±2.1) × 10 −4 fm 3 and β N = (2.5∓0.8∓2.1) × 10 −4 fm 3 in close agreement with the free-nucleon values.
