讨论了多体碎裂过程中碎片线动量的完全表征与多体系统空间波函数的等价性。我们的实验对三体解离的状态选择H3和D3分子到基态氢原子强烈建议存在这样一个密切的关系，因为它也是由理论预测的成像定理的形式。我们的结论是，谨慎的成像多体碎片提供了一个实验室视图的平方多体波函数在空间尺度的分子尺寸，在该片段退出到独立的自由粒子的领域。
The equivalence of a complete characterization of linear momenta of fragments from a many-body fragmentation process and the spatial wave function of the many-body system is discussed. Our experiment on three-body dissociation of state selected H3 and D3 molecules into ground-state hydrogen atoms strongly suggests the existence of such a close relationship as it is also predicted by theory in the form of the imaging theorem. We conclude that prudent imaging of many-body fragmentation provides a laboratory view of the squared many-body wave function at a spatial scale of molecular dimensions at which fragments exit into the realm of independent free particles.
