The particle spectrometer VElocity foR Direct particle Identification (VERDI) allows measurements of fission fragment (FF) mass distributions with a resolution from 1 to 2 mass units, by means of the detection of two fragment velocities and two fragment energies. VERDI consists of two arms with up to 32 Passivated Implanted Planar Silicon (PIPS) detectors and a Micro Channel plate (MCP) each....
The mechanism responsible for the generation of the large angular momenta observed in fission fragments is still a heavily discussed question in nuclear physics. Since they are not directly measurable, experimentally accessible observables are used to derive the angular momenta using nuclear model codes. One of these observables is the yield ratio between spin isomers produced in a fission...
n 2023, two experimental campaigns were performed at the PTB Ion Accelerator Facility in Braunschweig (Germany), in order to measure the delayed neutron macroscopic data in the fast neutron induced fission of 238U. In total, the delayed neutron yield was measured for 15 energies between 1.5 and 19 MeV. 3 measurements of the kinetics parameters associated to the delayed neutrons emission...
