“The Experimental Fission Program in Inverse Kinematics at GANIL”


 

Abstract: 

The fission process has intrigued physicist for a long time from both, experimental and theoretical approaches. From a qualitative point of view, it is well known that nuclear structure dominates the production of fission fragments at low excitation energy. However, the large deformation reached by the system and the fission dynamics that drives the system from one single object to two separated fragments prevent, so far, from a quantitave microscopic description of the problem.

A great effort has been made in the last decades in order to modeling the fission process, but the accuracy of these models could not be experimentally endorsed because of the limited number of available systems as well as a reduced number of physical observables.The ongoing fission program at running at GANIL provided new experimental data from exotic fissioning systems. The inverse-kinematics technique using a Uranium beam at Coulomb energies open new opportunities such as the measurement of the neutron content of fission fragments that reveals the configuration of the system at the scission point.

A global overview of this fission program at GANIL will be presented, including the most relevant results such as the experimental indications of the impact of octupole deformed shells at scission.
