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 ...

In this pioneering research, the team focused on nuclei with a proton number (Z) of 84 or higher and a neutron number (N) of 128 or more, employing semi-empirical formulas to calculate partial ...

How long does a free neutron really live before it decays? This simple question has annoyed physicists for decades. Moreover, when they searched for an answer, they found not one but two confusing ...

The neutron is composed of two down quarks and an up quark and is stable under the strong and electromagnetic interactions. The weak interaction, however, can convert a down quark into an up quark ...

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 ...

New research has enhanced scientists' understanding of how free neutrons decay into other particles. The work provides the first measurement of the energy spectrum of the photons that are released in ...

AT SOME point in our lives, most of us learn that atoms are comprised of three types of particle: neutrons, protons and electrons. Each has distinct properties. The electron and proton have opposite ...

(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 ...

ON bombarding uranium with neutrons, Fermi and collaborators 1 found that at least four radioactive substances were produced, to two of which atomic numbers larger than 92 were ascribed. Further ...

An international team of physicists has found strong evidence for the existence of a new ‘doubly magic’ nucleus with an unconventional configuration of neutrons. The oxygen–24 nucleus is also the ...

For four years, James Chadwick was a prisoner of war in Germany. When World War I ended, he returned to his native England to rejoin the mentor of his undergraduate days, Ernest Rutherford. Now head ...
