One of the drivers for this seminar series is to get a glimpse of the many research questions, ideas, and results linked to the activities in our division. The seminars are intended to be very informal and we make plenty of room for questions and discussions.

Abstract: One way to deepen the understanding of nuclear structure is by studying the gamma rays emitted by excited nuclei. These nuclei can be created using, for example, the fusion-evaporation reaction. As a result of this reaction, an enormous number of different nuclei are created, each with their own probability. The nuclei that are the easiest to produce in these reactions have been available for study for several decades and are well known by now. The most curious cases are then those ones that are scarcely created, but how does one find their signals from the massive background?
In this talk, I will describe the nature of gamma-ray spectroscopy and the methods that have been developed to study these difficult cases, including one of the most recently developed ones, recoil-beta tagging. I will also describe my work on developing and building a detector to be used with this method and how things can go in reality when one has to finish one’s PhD in a timely fashion.
