论文摘要
在冷方案中，光学状态准备和对齐分子的共振散射允许对双分子碰撞的最详细询问和控制。该技术最近已应用于使用Stark诱导的绝热拉曼通道技术在j = 2旋转水平上制备的两个对齐的ottho-d2分子的碰撞。在这里，我们为两个对齐分子的碰撞开发了理论形式主义，并将我们的方法应用于状态准备的D2（v = 2，j = 2） + d2（v = 2，j = 2，j = 2） - > d2（v = 2，j = 2，j = 2） + d2（v = 2，j = 0，j = 0）碰撞。量子散射计算是在准确的H $ _2 $ -H $ _2 $相互作用潜力上以全尺度进行的。实验角分布的关键特征被复制，主要归因于轨道角动量L = 4的部分波共振
Resonant scattering of optically state-prepared and aligned molecules in the cold regime allows the most detailed interrogation and control of bimolecular collisions. This technique has recently been applied to collisions of two aligned ortho-D2 molecules prepared in the j=2 rotational level of the v=2 vibrational manifold using the Stark-induced adiabatic Raman passage technique. Here, we develop the theoretical formalism for collisions of two aligned molecules and apply our approach to state-prepared D2(v=2,j=2) + D2(v=2,j=2) --> D2(v=2,j=2) + D2(v=2,j=0) collisions. Quantum scattering calculations were performed in full-dimensionality on an accurate H$_2$-H$_2$ interaction potential. Key features of the experimental angular distributions are reproduced and attributed primarily to a partial wave resonance with orbital angular momentum L=4
