The precise measurement of an exotic atom in the laboratory has refined scientists’ understanding of neutron stars, which are among the universe’s most extreme objects. The study, published January 22 ...

An international team of nuclear physicists has created zinc-54 for the first time. Moreover, they have confirmed that it can undergo two-proton decay, a rare process that has only been seen in one ...

IN a previous letter 1 we described the measurement of the half-lives of a few elements made weakly radioactive by neutron bombardment. The same neutron source and method have been used to investigate ...

For more than half a century, the 1,000-foot-diameter spherical reflector dish at the Arecibo Observatory in Puerto Rico was the largest radio telescope in the world. Completed in 1963, the dish was ...

Engineers rely on neutrons to peer inside advanced materials and devices such as fuel cells to better understand and improve them. But a critical shortage of a rare form of helium (helium-3) used for ...

Scientists have long known that, compared with Earth, the moon is much poorer in what study leader Frédéric Moynier calls "moderately volatile" elements such as sodium, potassium, zinc, and lead. But ...
