What can we learn about fission in the 21st century?
In the last two decades, through technological, experimental and theoretical advances, the situation in experimental fission studies has changed dramatically. With the use of advanced production and detection techniques much more detailed and precise information can now be obtained for the traditional regions of fission research. Crucially, new regions of nuclei have become routinely accessible for fission studies, by means of radioactive ion beams.
The talk will briefly introduce classical concepts of fission, followed by examples of novel developments in fission techniques, in particular the emerging use of inverse-kinematic approaches, both at Coulomb and relativistic energies e.g. at FRS (GSI), and VAMOS (GANIL, France), and of fission studies with radioactive beams.
The emphasis on the fission-fragment mass and charge distributions will be made for low-energy fission, also as a function of excitation energy. Such studies have become possible due to the development of several complementary experimental studies, including the β-delayed fission with laser-ionized mass-separated radioactive beams at ISOLDE(CERN) and multinucleon transfer reactions, e.g. at JAEA-Tokai(Japan).
The talk will conclude with the discussion of the new experimental fission facilities which are presently being brought into operation, along with promising 'next-generation' fission approaches, which might become available within the next decade.
About the speaker：
Andrei Andreyev is a professor at the School of Physics, Engineering and Technology, University of York, UK. He graduated from Moscow State University and earned his PhD from the Flerov Laboratory of Nuclear Reactions at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. His research focuses on nuclear and laser spectroscopy with radioactive ion beams (RIBs), fission, and nuclear reactions, including shape coexistence, particle and gamma decay, laser-assisted nuclear decay studies, fission and beta-delayed fission, and transfer and Coulex reactions.
