Seated at the head of the periodic table, hydrogen is the lightest element, a minimalist atom consisting only of a proton and an electron. It is not scarce: three-quarters of the mass of the ...

But a few years back, researchers put a heavier version of the electron, called a muon, in orbit around a proton. This formed an exotic, heavier version of the hydrogen atom.

This is precisely the difference between the new, smaller, dimension of the proton, the nucleus of the hydrogen atom, and the value which has been assumed so far. Instead of 0.8768 femtometres it ...

Operators of the world's largest atom smasher say they will try to collide proton beams at record high energy in one week. The European Organization for Nuclear Research, or CERN, says beams have ...

Explore the fundamental components of an atom: protons, neutrons, and electrons. This video discusses why the traditional model of the atom is inaccurate, highlighting the unpredictable nature of ...

Scientists say the world's largest atom smasher has broken the record for proton acceleration, sending beams of the particles at 1.18 trillion electron volts.

The world's largest atom smasher broke the record for proton acceleration Monday, sending beams of the particles at 1.18 trillion electron volts around the massive machine.

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 metre. This video also looks at the basic parts of an atom (protons, neutrons and electrons) and why the ...

Proton-coupled electron transfer (PCET) reactions play a vital role in a wide range of chemical and biological processes. Recent advances in the theory of PCET will be presented. The quantum ...

Sørensen and colleagues compared their findings to previous studies of normal-tissue damage from proton irradiation, both in the entrance plateau and using the spread-out Bragg peak (SOBP). DMF values ...
