Most of the universe is made up of hydrogen and helium atoms, which came into being after the Big Bang cooled down a little. Heavier atoms are formed during high-energy collisions in stars.

The U.S. Department of Energy-funded site sits on 5,265 acres in Suffolk County and is so vast it has its own ZIP code — ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

Though atomic nuclei are often depicted as static clusters of protons and neutrons (nucleons), the particles are actually ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying ...

Physicists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have reported the first observation and spectroscopy of aluminium-20, a ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through ...

Physicists have made a groundbreaking discovery by identifying a brand-new, highly unstable form of aluminum—called ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics experiments that changed the world. Physics experiments have changed the world ...

Dynamic 16K random access memories (RAMs) have been irradiated with neutrons having mean energies of 6.5, 9 and 14 MeV and with 32 MeV protons and have been found to undergo single event upset. For ...

A proton recoil method along with Silicon Carbide semiconductor detector is presented in this paper. It consist of hydrogenous converter layer to generate recoil protons by means of neutron elastic ...
