And if neutrons do, in fact, decay into some kind of dark matter particle, it could solve the mystery of dark matter. But for now all we know is that these two results don't agree, and we need to ...

A new detector at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has successfully observed ...

When a neutron beam passes through a slit its transverse motion is quantized, just like a particle in a box. Indeed, for the experimental ... A thermal beam of neutrons from the ILL reactor was ...

To generate the number of neutrons the researchers observe would take about 10 million gamma ray photons m-3 s-1. Unfortunately, lightning strikes only generate a tiny fraction of that.

However, neutrons in stable nuclei last indefinitely. To date, the world’s best value for the neutron lifetime—a term indicating how quickly a population of free neutrons decays—is 886.7 ...

In the cores of neutron stars, the crushing pressures can squeeze apart atomic nuclei, and maybe even protons and neutrons themselves. Neutron stars' surface gravities are so intense that the ...

The strongest force in the Universe is the one that holds together the protons and neutrons in an atom’s nucleus. To unlock how elements are forged, the physics of neutron stars and more ...

The neutrons’ lack of charge and long lifetime minimized the effect of forces other than gravity. Classically, the energy spread of the bouncing neutrons – and so the range of heights to which they ...

Using a high-powered laser to generate pulses of neutrons 100 nanoseconds long, a test on samples of silver and tantalum successfully returned characteristic information for both materials and ...

In quantum physics, neutrons are said to be made of three smaller particles called quarks: one "up" quark with a charge of +2/3, and two "down" quarks with a charge of -1/3, not, as originally ...

The skin of lead-208 — a variety of lead with 126 neutrons in addition to its 82 protons — is about 0.28 trillionths of a millimeter thick, researchers report online April 27 in Physical ...
