Nuclear fission is a process in which a heavy nucleus split into two. Most of the actinides nuclei (plutonium, uranium, curium, etc) fission asymmetrically with one big fragment and one small. Empirically, the heavy fragment ...

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted ...

What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case ...

In a paper published today in Nature Physics , the ALICE collaboration reports that proton collisions sometimes present similar patterns to those observed in the collisions of heavy nuclei. This behaviour was spotted through ...

The nuclei of atoms of heavy elements are not necessarily spherical; they may be variously extended or flattened along one, two or even three axes. An international team of physicists, led by scientists from the Institute ...

The hottest matter that existed in the early universe after the Big Bang is created in collisions of high-energy nuclei. Using information on the propagation and attenuation of fast particles coming from the collisions, nuclear ...

When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons, a similar process, the elastic collision, has never been observed. Physicists from the Institute of Nuclear ...
