Scientists have learned more about the subatomic particles known as neutrinos, sometimes called ghost particles. They’re known for traveling at near lightspeeds and being nearly massless, but a recent ...

The 12-metre-diameter acrylic vessel surrounded by 9,000 photomultiplier tubes at the heart of the the Sudbury Neutrino Observatory and SNO+ experiments (SNOLAB) The name is given to neutrinos, which ...

Scientists say they have made a major breakthrough in detecting “ghost particles”. The name is given to neutrinos, which are one of the most mysterious particles in the universe and remain largely ...

Scientists have managed to observe solar neutrinos carrying out a rare atomic transformation deep underground, converting carbon-13 into nitrogen-13 inside the SNO+ detector. By tracking two faint ...

Atomic nuclei are often described as orderly systems. Certain numbers of protons or neutrons, called magic numbers, usually produce especially stable and spherical nuclei. These numbers fill entire ...

Learn how a particle born in the sun’s core left a measurable flash of light two kilometers beneath Earth’s surface. Neutrinos are perhaps the most elusive particles in physics. Born in the nuclear ...

Exotic atoms and molecules are forms of basic matter in which one subatomic particle is replaced by another with the same charge. For instance, an electron can be replaced with a muon, a pion or an ...

IN 1940, we prepared the isotope of mass 211 of element 85 by bombarding bismuth with alpha particles accelerated in the 60-in. cyclotron of the Radiation Laboratory of the University of California 1.
