Sometimes, a few seconds after the fission occurs in a nuclear chain reaction, additional neutrons are released. Fission fragments are typically radioactive, and can emit different types of ...

In a breakthrough that could pave the way for more efficient and cleaner energy, researchers at Chalmers University of Technology in Sweden have discovered a rare phenomenon that changes what we know ...

Third, the rupture is the fastest stage of fission dynamics, starting from the capture of the incident neutron and formation of the compound nucleus, until all fission fragments have been emitted.

The by-products include free neutrons, photons usually in the form gamma rays, and other nuclear fragments such as beta particles and alpha particles. Fission of heavy elements is an ...

An international team of researchers, including scientists from Science Tokyo, has developed a five-dimensional ...

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...

The fragments fly apart with considerable speed and, ... THE fission process can be briefly described as follows. A neutron is captured by a nucleus of uranium 235, ...

An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where nuclear fission is predominantly governed by an asymmetric ...

Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Until now.

Fission releases energy when a large uranium nucleus splits into two radioactive fragments, which carry the energy as they fly apart. Fusion, by contrast, relies on the universe’s smallest atom ...

AT the Physical Society's Conference on Fundamental Particles, held at Cambridge in July 1946, we reported that a light charged particle is occasionally emitted in the fission of uranium by slow ...
