The Magnetic Field

Abstract In this paper we study the problem of fermions scattering by the field of a magnetic dipole in Minkowski space-time. The amplitude and differential cross section for scattering of massive fermions are obtained using the exact solution of the Dirac equation written in the helicity basis. We found that the most probable transitions are those that scatter the fermions perpendicular to the direction of the magnetic field and we consider only the transverse momenta in our analysis. The differential cross section behavior in terms of scattering angle and energy is graphically analysed and we perform a comparative study with the Coulomb scattering.

Theoretical Results

The coherent to Compton differential cross section ratios were calculated for elements in the range 20 ≤ Z ≤ 32 under an external magnetic field. The elements were irradiated by 59.54 keV gamma rays from an 241Am radioactive source. A Si(Li) detector was used to detect the scattered photons. It was observed that the coherent to Compton differential cross section ratios of the samples increase with the magnetic field (B = 0, 0.4, and 0.8 T). The theoretical results were obtained with two different methods and compared with the experimental results at 0 T.

Sensitive Testing

It is pointed out that the y-dependence of the differential cross-section for various types of neutrinos on the electron promises to be a sensitive testing ground of the electroweak Standard Model at KAON in Vancouver. Estimates of the flux requirements are given and the feasibility of such experiments is discussed.
