- Fissility of actinide nuclei by 60-130 MeV photons Viviane Morcelle Odilon A. P. Tavares Física, Astronomía y Matemáticas Nuclear fissility Photofission reaction Nuclear fissilities obtained from recent photofission reaction cross section measurements carried out at Saskatchewan Accelerator Laboratory (Saskatoon, Canada) in the energy range 60-130 MeV for 232Th, 233U, 235U, 238U, and 237Np nuclei have been analysed in a systematic way. To this aim, a semiempirical approach has been developed based on the quasi-deuteron nuclear photoabsorption model followed by the process of competition between neutron evaporation and fission for the excited nucleus. The study reproduces satisfactorily well the increasing trend of nuclear fissility with parameter Z²/A. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413543011 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4b Vol.36
