Access to Scission Observables from Fission Fragment Velocities

Experimental measurements of the products of fission reactions are generally biased by evaporation stages before and after the fission process. Its complexity needs as many observables as possible to check the present models and reveal new correlations. Fully identified fission fragments and their velocities can provide new information as well as be a probe for current descriptions and models. By means of momentum conservation, the measured velocities provide information on mass, total kinetic energy, and geometrical configuration at scission.
