(Inside Science) — Scientists have been trying to measure the lifetime of a neutron outside an atomic nucleus for decades, and for the last 15 years, two types of laboratory experiments have provided ...

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four ...

A few days ago I wrote about how different measurements of the Hubble parameter gave results that didn't quite agree. It's not the only example of such an experimental disagreement. In fact, one of ...

An international team of researchers recently measured the lifetime of a neutron outside of an atomic nucleus with extraordinary precision. By their measurements, the neutron survived for 14.629 ...

A neutron decays into a proton, an electron, and an antineutrino. In the QCD lattice approach, a discrete space is used for the calculation. The different colours on the lattice represent the gluons ...

All the matter we know of in our Universe is made of both fundamental and composite particles. However, only a few of the fundamental particles are observed to be stable and not to decay into other ...
