The structure of fission barriers in actinide nuclei is characterized by pronounced multi-humped shapes, which give rise to long-lived isomeric states trapped in secondary minima of the potential-energy surface. These complex barrier profiles emerge from the interplay between macroscopic liquid-drop behavior and microscopic shell effects. In the region around the deformed magic neutron number...

8. New experimental insights into the "Thorium anomaly" from isotopic fission fragment yields of 232Th produced in inverse-kinematics

Since the discovery of fission in 1939, several theoretical models were developed to properly explain the observations [1]. It wasn’t until the introduction of shell effects by Strutinsky [2], that the microscopic - macroscopic models [3] could match the measured yields of heavy actinides like 252Cf or 254Es [4]. The interplay between both quantities prevents, so far, from a fully...
