　　讲座内容摘要：

　　Describing the complete reaction leading to the synthesis of super-heavy elements is still a challenge. One of the reasons is the so-called fusion hindrance phenomenon that is well understood qualitatively but not quantitatively. Moreover, no consensus has been reached yet regarding the models calculating the formation probability from the contact point of the two colliding nuclei to the compound shape that is responsible of the fusion hindrance. Consequently, there are large discrepancies spanning few orders of magnitude in the predictions of various models. Some differences come from the parameters and some from the models.

　　Parameters can be assessed and constrained by an uncertainty analysis. With the current state of the art models and methods of analysis, we will show how uncertainty analysis can guide further researches and try to estimate the best possible predictions.
