标题： Spin interaction of non-relativistic neutrons with an ultrashort laser pulse

摘要： 非相对论性泡利方程用于研究慢中子与短磁脉冲的相互作用。 在极限情况下，脉冲仅在某一瞬间作用于中子的磁矩。 我们通过推导泡利波函数在脉冲处的连接条件来获得散射振幅。 给出了受空间恒定磁场均强脉冲作用的极化平面波中子束的显式表达式。 假设磁场由超短激光脉冲产生，我们提供了粗略的数值估计。 显示英文摘要

摘要： The non-relativistic Pauli equation is used to study the interaction of slow neutrons with a short magnetic pulse. In the extreme limit, the pulse is acting on the magnetic moment of the neutron only at one instant of time. We obtain the scattering amplitude by deriving the junction conditions for the Pauli wave function across the pulse. Explicit expressions are given for a beam of polarized plane wave neutrons subjected to a pulse of spatially constant magnetic field strength. Assuming that the magnetic field is generated by an ultrashort laser pulse, we provide crude numerical estimates.
