Abstract

In the Born approximation, expressions are obtained for the angular and energy distribution of bremsstrahlung photons emitted by relativistic neutrons in the field of a nucleus that has an electric quadrupole moment, and magnetic dipole and octupole moments. The expression obtained for the cross section (dσ=dσE+dσM) describes the total electromagnetic bremsstrahlung of the neutrons due to the interaction of the magnetic moment of the neutron with the electric (Ze, Q) and magnetic (μI, ω) multiple moments of the target nucleus. It is shown that in contrast to the bremsstrahlung of electrons the bremsstrahlung cross section of neutrons does not contain an infrared divergence. The application of the formulas to9Be and27Al nuclei is considered. The results are used to investigate the electromagnetic emission of neutral Fermi particles with spin 1/2 and can be used to obtain additional information about the interaction of their magnetic moment with the multiple moments of a nucleus of arbitrary spin.
