THE MOST COMPACT SCISSION CONFIGURATION OF FRAGMENTS FROM LOW ENERGY FISSION OF 234U AND 236U Modesto Montoya Zavaleta DOI: https://doi.org/10.33017/RevECIPeru2009.0001/ RESUMEN Usando una técnica de tiempo de vuelo, Signarbieux et al. midieron el valor máximo de la energía cinética total en función de la masa primaria de los fragmentos de la fisión de baja energía de 234U y 236U. De los cálculos de las configuraciones de escisión, puede concluirse que, para esos dos sistemas físiles, el valor máximo de la energía cinética corresponde a las fragmentaciones 42Mo62, 50Sn80 y 42Mo64, 50Sn80), respectivamente, son iguales a los valores disponibles de energía, y sus configuraciones de escisión están compuestas por un fragmento pesado esférico y un fragmento liviano prolato, ambos en sus estados fundamentales. PALABRAS CLAVE: Fisión a baja energía; 234U; 236U; energía cinética de fragmentos; fisión fría. ABSTRACT Using a time of flight technique, the maximal values of kinetic energy as a function of primary mass of fragments from low energy fission of 234U and 236U were measured by Signarbieux et al. From calculations of scission configurations, one can conclude that, for those two fissioning systems, the maximal value of total kinetic energy corresponding to fragmentations (42Mo62, 50Sn80) and (42Mo64, 50Sn80) respectively, are equal to the available energies, and their scission configurations are composed by a spherical heavy fragment and a prolate light fragment both in their ground state. Keywords: Low energy fission; 234U; 236U; fragment kinetic energy; cold fission.

A two-center parametrization with smoothed neck is used to describe the shapes during the fission process of 234 U in a wide range of mass asymmetry (cold fission with 100 Zr fragment, 28 Mg radioactivity and α-decay). The optimum fission path has been found by minimizing the action integral. The neck influence is stronger for lower mass asymmetry.
