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 ...

Physicists have solved a long-standing puzzle about mercury’s nuclear fission by using a five-dimensional model that ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, which was discovered in 1938, occurs when a neutron hits the atomic nucleus. It splits, producing two lighter elements and, more importantly, a few neutrons and some energy — both of ...
