Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude ...

When researchers blasted lead-208 with ions to excite the subatomic particles and determine the shape of the nucleus, they found that it was instead sort of oblong, as if it had been squashed.

Physicists recorded the lowest-energy neutrino event yet, using signals from the particles’ antimatter counterpart produced ...

A relatively small detector caught neutrinos from a nuclear reactor using a technique known as coherent scattering ...

the proton and beryllium 7 nucleus as a function of the distance between them. This probability depends on the distribution of protons inside boron 8, which is high for ...

Their achievement cemented the theory of quantum chromodynamics, or QCD, which describes the interactions of quarks and other subatomic particles inside the nucleus.

In a nucleus, for example, the motion of the protons and neutrons approaches the speed of light. This also applies to the probes that nuclear physicists use to learn more about those particles.

Subatomic particles called muons are born from cosmic rays bombarding the atmosphere. Because muons can penetrate objects, scientists are using them to peek inside volcanoes. This technique ...

Physics & Mathematics Particle Physics Scientists tried to solve the mystery of the helium nucleus — and ended up more confused than ever ...

The mechanism also suggested a state of matter exists in neutron stars that is "non-nuclear," in which quarks are allowed to exist "deconfined" in protons, neutrons and other particles.

protons inside boron 8, which is high for small distances and becomes smaller at large distances. “The distribution has the shape of a hill,” Gagliardi says, “with the ...
