Nuclear fission with radioactive ion beams

Speakers: Andreï Andreyev (Univ. York)

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  at FRS (GSI), SAMURAI (RIKEN, Japan), and VAMOS (GANIL, France)  and of fission studies with radioactive beams [1].
 
The emphasis on the fission-fragment mass and charge distributions will be made for low-energy fission. 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) [2,3].
 
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 [1].
