The effects of laser-induced pre-alignment on the deflection of paramagnetic molecules by inhomogeneous static magnetic field are studied. Depending on the relevant Hund's coupling case of the molecule, two different effects were identified: either suppression of the deflection by laser pulses (Hund's coupling case (a) molecules, such as ClO), or a dramatic reconstruction of the broad distribution of the scattering angles into several narrow peaks (for Hund's coupling case (b) molecules, such as O(2) or NH). These findings are important for various applications using molecular guiding, focusing and trapping with the help of magnetic fields.
研究了激光预对准对非均匀静态磁场中顺磁分子偏转的影响。根据分子的相关洪德耦合情况，确定了两种不同的影响：激光脉冲对偏转的抑制（如 ClO 等 Hund's 耦合情况（a）分子），或散射角宽分布的剧烈重构为几个窄峰（如 O(2) 或 NH 等 Hund's 耦合情况（b）分子）。这些发现对于利用磁场进行分子引导、聚焦和捕获的各种应用非常重要。
