Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. ​ But are the nuclei of atoms ...

The shape of nuclei affects all aspects The shape of a nucleus, the central core of an atom, plays a crucial role in nearly all aspects of nuclear behavior and processes. Therefore, this research ...

Carbon atoms have 6 protons and 6 neutrons in their nuclei, helium goes 2 for 2, though hydrogen has just the one proton and no neutrons. That makes it the smallest atom at a mere 106 picometers ...

The atom is neutral as it has two positive protons ... is the splitting of a large atomic nucleus into smaller nuclei. The fast-moving neutrons carry most of the energy from the reaction with ...

A particle that lacks the energy to climb a barrier can still appear on the far side, a curiosity known as “quantum tunneling.” ...

Subtle quantum effects within atomic nuclei can dramatically affect how some nuclei break apart. By studying 100 isotopes ...

The only difference between a lead atom and a gold atom is three protons ... They accelerated beams of lead nuclei to near light speed and smashed them into each other. When these high-speed ...

Many atomic nuclei have a magnetic field similar to that ... all but one of the initially 83 electrons must be stripped off the atom to generate the hydrogen-like system. The fragments circle ...

The ancient dream of turning lead into gold is now a reality – but it’s not quite what the alchemists might have hoped for.

A team of physicists at the Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) has achieved a breakthrough in the study of atomic nuclei. They have discovered that uranium ...
