Coulomb and even-odd effects in cold and super-asymmetric fragmentation for thermal neutron induced fission of U-235
(Instituto Peruano de Energía NuclearPE, 2016-05)Acceso abiertoThe Coulomb effects hypothesis is used to interpret even-odd effects of maximum total kinetic energy as a function of mass and charge of fragments from thermal neutron induced fission of U-235. Assuming spherical fragments ... -
Coulomb effects in cold fission
(LimaPE, 1986-02)Acceso abiertoThe structures in the mass and total kinetic energy (TKE) distributions in cold fission of U-234 and U-236 are interpreted in terms of the Coulomb interaction energy (C) between fragments at the scission point. The maximal ... -
Coulomb effects in isobaric cold fission from reactions 233-U(nth,f), 235-U(nth,f), 239-Pu(nth,f) and 252-Cf(sf)
(LimaPE, 2014-11)Acceso abiertoThe Coulomb effect hypothesis, formerly used to interpret fluctuations in the curve of maximal total kinetic energy as a function of light fragment mass in reactions 233-U (nth,f), 235-U(nth,f) and 239-Pu(nth,f), is confirmed ... -
Effects of variations on slopes of yield and average kinetic energy curves as a function of fragment mass on standard deviation of final kinetic energy distribution from thermal neutron induced fission of U-235
(Lima (Perú)PE, 2007-08)Acceso abiertoThe mass and kinetic energy distributions of fragments from thermal neutron induced fission of U-233 have been studied using a Monte-Carlo simulation. In our previous work [1] we reproduce the two pronounced broadenings ... -
Fragmentaciones frías en la fisión inducida por neutrones térmicos del Pu-239

Influencia de la emisión de neutrones en la medición por el método de la doble energía de la distribución de masa y energía cinética de los fragmentos de la fisión espontánea del Cf-252
(Instituto Peruano de Energía NuclearPE, 2011-10)Acceso abiertoEl método de doble energía ha sido usado por varios autores para medir la distribución de masa (A*) y energía cinética total de los fragmentos complementarios (EKT*) de la fisión espontánea del Cf-252, encontrándose un ... -
Monte Carlo Simulation to relate primary and final fragments mass and kinetic energy distribution from low energy fission of U-234
(Lima (Perú)PE, 2008-11)Acceso abiertoThe kinetic energy distribution as a function of mass of final fragments (m) from low energy fission of U-234, measured with the Lohengrin spectrometer by Belhafaf et al., presents a peak around m = 109 and another around m ... -
Monte-Carlo simulation for fragment mass and kinetic energy distributions from neutron induced fission of U-235
(LimaPE, 2003-07)Acceso abiertoMass and kinetic energy distribution of nuclear fragments after neutron induced fission of U-235 have been studied using a Monte-Carlo simulation. Besides that the pronounced peak in the standard deviation of the kinetic ... -
Neutron emission effects on fragment mass and kinetic energy distribution from fission of Pu-239 induced by thermal neutrons
(Instituto Peruano de Energía NuclearPE, 2010-11)Acceso abiertoThe average of fragment kinetic energy (<E*>) and the multiplicity of prompt neutrons (v) as a function of fragment mass (m*), as well as the fragment mass yield (Y (m*)) from thermal neutron induced fission of Pu-239, have ... -
Schematic model of two hard cores for cold fission
(LimaPE, 1990-07)Acceso abiertoStructures in mass and total kinetic energy distribution (TKE) in cold fission of U-234, U-236, and Pu-240 are interpreted in terms of a static scission configuration model. The role of shells in fragments present in their ... -
Simulación de un experimento para medir la distribución de la energía cinética de fisión inducida por neutrones térmicos del U-235
(PE, 2002-06)Acceso abiertoUno de los datos necesarios para el estudio del proceso de fisión de núcleos actínidos es la configuración de los fragmentos en momento de la escisión. Esta configuración corresponde a un determinado valor de energía ... -
The most compact scission configuration of fragments from low energy fission of U-234 and U-236
(Instituto Peruano de Energía NuclearPE, 2010-04)Acceso abiertoUsing a time of flight technique, the maximal values of kinetic energy as a function of primary mass of fragments from low energy fission of U-234 and U-236 were measured by Signarbieux et al. From calculations of scission ...
