62. Fission in inverse kinematics – history, status and outlook

invited

The use of radioactive beams in inverse kinematics has a strong impact on nuclear physics research and nuclear fission is no exception. Nuclear fission is a quite complex process with a large number of observables, such as fission fragment charge and mass distributions, multiplicities and energies of evaporated neutrons and gamma-rays, released total kinetic energy, fission cross sections and...

Isomeric yield ratios (IYRs) are key observables in nuclear fission, as they provide insight into the angular-momentum distribution of primary fission fragments. Accurate IYR data are also essential for modeling the r-process in stellar nucleosynthesis and for determining the antineutrino mixing angle from reactor spectra. In addition, IYRs play a role in nuclear-energy applications, including...

The Oslo Cyclotron Laboratory (OCL) at the University of Oslo is developing a comprehensive experimental program focused on advancing our understanding of nuclear fission. Leveraging the existing cyclotron infrastructure and state-of-the-art detection systems such as OSCAR [1, 2], this program aims to investigate prompt fission gamma emission and the interplay between nuclear structure and...

20. Transfer-induced fission at the ISOLDE Solenoidal Spectrometer

The study of nuclear fission remains a critical area of research, not only for advancing our understanding of fundamental nuclear processes but also for its implications in the synthesis of heavy elements in astrophysical environments. In the context of r-process nucleosynthesis, fission plays a pivotal role by limiting the mass of nuclei that can be produced. However, data on the fission...

7. Very asymmetric fission yields of U-233(n,f) at LOHENGRIN

Marius Torsvoll (University of Oslo)

contributed 12+3

In this work we report on a fission yield experiment done with the LOHENGRIN recoil mass spectrometer. Understanding the dynamics of nuclear fission requires accurate knowledge of the charge and mass distributions of fission fragments, particularly in rare and poorly studied regions. We present a dedicated investigation of the assymetric fission yields in 233U(n$_{th}$,f), targeting fragment...
