Systematic study of fission modes in the proton-induced fission of actinide and pre-actinide

Abstract

The systematic analysis of several measured fragment mass distributions from different fission reactions available in the literature is presented. Data of proton-induced fission on Am 241

Efeitos do movimento coletivo na evaporação e fissão nuclear

“…This code has been developed for more than three decades [5,21,22,23,24,25] and has been used to study very different nuclear reactions with success. A lot of good agreements are obtained between experiment and CRISP results for photon-, proton-and electron-induced fission reactions [26,27,28,29,30,31,32,33,34,35,36]. Also there are some applications of CRISP, especially for nuclear reactions, where we apply the model with success to develop new concepts of nuclear reactors [37,38,39,40,41].…”

“…While applying this mechanism for the reaction of 11 B ion with 209 Bi at 146 MeV results in a fairly good agreement between the CRISP and experimental data, 5.4. Fissility 68 [32,35,84], but it was not tested before for the case of nucleus-nucleus reactions, when the high angular momentum can introduce important effects, as we observed in the case of fission.…”

“…photons, protons and electrons[27,21,22,23,24,25,37,35], and recently, has been extended to consider heavy ions as the incident projectiles. The mechanism of heavy-ion induced nuclear reactions has been covered in a new branch of the Monte Carlo CRISP code in the framework of the rotating liquid drop model.In the intranuclear cascade stage, we are restricted to the collision of spherical-spherical nuclei.…”
