In the exit channel of nuclear fission

Abstract: The final period of nuclear fission is discussed. We propose the following picture: Nuclear scission happens because of an hydrodynamic instability triggered by random surface vibrations. Thus the scissioning complex ruptures at random positions. Measured total kinetic energies point to the very relevance of the instability, while the randomness of rupture shows up in neutron emission data. A Principal Difficulty with Present Fission TheoriesThere are presently two models for the description of nuclear fission… Show more

“…The former because it produces fragments with strong prolate deformations, the latter because o f pear-shaped deformations. All deformations should be transformed to heat, and heat finally causes neutron emission [15]. Peaks in the neutron m ulti plicity for nearly symmetrical fission o f 252C f have been observed by Zakharova and Ryazanov at low and high total kinetic energies (Fig.…”

“…These effects may be included e.g. by the gaussian smoothing [22] or by applying the random neck rupture (rnr) mechanism [33][34][35][36]. In the latter method, for each pre-scission shape corresponding to the scission configuration (Q sc 20 , Q sc 30 ) the probability of splitting of a nucleus at the certain position on the symmetry axis OZ along the neck is evaluated.…”

“…Once fitted it reproduces wide range of experimental fission results. The main inspiration for our investigations is the idea proposed by U. Brosa et al [14,15,16]. The authors assume direct dependence of fragment mass distribution on the random neck rupture mechanism of mother nucleus in its pre-scission shape.…”
