Description
Nuclear fission results in two excited fragments which de-excite very quickly via the emission of prompt neutrons and gamma rays. These emissions can be detected and contain a wealth of information about the fission process itself, especially from the correlations between the emitted particles. The particular difficulty in studying fission is that this emission occurs from two moving sources at almost the same point in space and at the same time. There are many experimental approaches available to help understand the fission process [1][2][3], and of particular relevance is the role of angular momentum. In this presentation the focus will be on the technique of high-resolution gamma ray coincidence spectroscopy both within a particular fragment and between fragment partners. The information that can be extracted will be reviewed, along with the limitations of the approach, and future promising avenues of research will be outlined.
