Mediante la simulación con el método Monte-Cario se estudia la distribución de masas y sus respectivas energías cinéticas de los fragmentos de fisión nuclear del 235U inducida por neutrones. Además de reproducir un pico pronunciado en la desviación standard de la energía cinética crE(m) en las cercanías de los fragmentos de masa m =109, nuestra simulación también produce un segundo pico alrededor de m =126. Estos resultados se encuentran en buena concordancia con los datos experimentales obtenidos por Belhafaf et al.8 Concluimos que los resultados obtenidos son consecuencia de las características de la evaporación neutrónica de los fragmentos y de la variación brusca de la curva de rendimiento de masas primarias.

Kinetic Energy Distributions

Within the 2-center shell model we present an explanation for the mass and total-kinetic-energy distributions of fission products of very heavy nuclei called “bimodal fission.” For the case of 258 FM we show that the symmetric fission can be described by a 2-dimensional treatment of the elongation and neck degree of freedom. Owing to shell corrections the system fissions via two decay channels that have distinct kinetic energies.

Abstract Correlated momentum and kinetic energy distributions of two photoelectrons in laser-assisted two-color two-photon double ionization of helium are investigated by numerically solving a one-plus-one dimensional time-dependent Schr\"{o}dinger equation (TDSE). We find that the weak assisting laser field can act as an energy transferring field, resulting in burst of double ionization. More importantly, the participation of the laser photon into the double ionization reshapes the correlation patterns in the momentum and kinetic energy distributions. The laser photon can be absorbed by any one of the two electrons, providing two channels that induces destructive interference in the correlated momentum and kinetic energy distributions, which is never found in previous work.
