双原子分子多光子解离电离产生的离子碎片的角分布具有明显的各向异性。场电离，库仑爆炸模型内的计算表明，实验结果（脉冲50 fs的强度）可以解释，而不调用重新定向的分子轴。另一方面，打火机和分子的碎片显示出被强迫排列的明显迹象。
The angular distribution of the ionic fragments from multiphoton dissociative ionization of diatomic molecules shows a pronounced anisotropy. Calculations within the field-ionization, Coulomb explosion model show that the experimental results (pulses of 50 fs at an intensity of ) can be explained without invoking reorientation of the molecular axis. The fragments of the lighter and molecules, on the other hand, show clear signs of being forced into alignment.
