利用符合三维动量成像技术研究了乙炔单阳离子和双阳离子的强超快激光诱导异构化和二体碎裂。虽然绝大多数以前的工作，强场异构化和碎片的乙炔必然涉及电离，通过专注于离子束目标的解离，我们确保一个单一的分子离子物种内的动力学随之而来，可能简化解释。我们展示了丰富的信息，可以从这样的测量，并讨论这种方法的优点和缺点。
We investigate intense, ultrafast laser-induced isomerization and two-body fragmentation of acetylene monocations and dications using coincidence three-dimensional momentum imaging. Whereas the vast majority of previous work on strong-field isomerization and fragmentation of acetylene has necessarily involved ionization, by focusing solely on dissociation of ion-beam targets, we ensure that the dynamics ensue within a single molecular ion species, potentially simplifying interpretation. We demonstrate the rich information that can be extracted from such a measurement and discuss advantages and disadvantages of this approach.
