Nuclear fission Wikipedia In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller, lighter nuclei.The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on Nuclear chain reaction Wikipedia A nuclear chain reaction occurs when one single nuclear reaction causes an average of one or subsequent nuclear reactions, this leading to the possibility of a self propagating series of these reactions The specific nuclear reaction may be the fission of heavy isotopes e.g uranium , U The nuclear chain reaction releases several million times energy per reaction than any Nuclear Fission vs Fusion Nuclear Power Nuclear Fission Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts lighter nuclei The fission process often produces free neutrons and photons in the form of gamma rays , and releases a large amount of energy.In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process. .

Elements of Fission Weapon Design The most likely fission neutron energy is around . MeV, but the average value, due to the long tail to the right, is very close to MeV Nuclear cross sections measure the likelihood of a nuclear reaction occurring, and are the effective geometric area the nucleus presents for that reaction. Fission nuclaire Wikipdia La fission induite a lieu lorsqu un noyau lourd capture une autre particule gnralement un neutron et que le noyau ainsi compos se dsintgre alors en plusieurs fragments. La fission induite de l uranium par absorption d un neutron est la raction de ce type la plus connue.
