Native frames: Separating sequential from concerted three-body fragmentation

POSTER

Abstract

During the fragmentation of polyatomic molecules, two or more bonds may break in a sequential manner. To interpret the multi-body breakup, it is beneficial to separate the concerted from the sequential fragmentation contributions. Recently, we proposed the native frames method to accomplish this goal, using the strong-field three-body fragmentation of OCS as an example [PRL \textbf{120}, 103001 (2018)]. This method allows us to separate the contributions of sequential breakup in any observable derived from the measured three-dimensional momentum distributions by exploiting the rotation of the intermediate moiety. In this poster, we will highlight results from a few polyatomic molecules using strong-field ionization as well as single-photon double ionization.
