摘要

摘要本文研究了闵可夫斯基时空中磁偶极子场对费米子的散射问题。利用狄拉克方程在螺旋基下的精确解,得到了大质量费米子散射的振幅和微分截面。我们发现最可能的跃迁是那些垂直于磁场方向散射费米子的跃迁,我们在分析中只考虑横向动量。用图形分析了散射角和能量的微分截面行为,并与库仑散射进行了比较研究。

Scattering of Fermions by a Magnetic Dipole 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.
