Einsteinium-255, produced through irradiation in ILL’s high-flux reactor, provided a continuous supply of fermium-255, ...

In a surprising turn of events, an international team of scientists has found that lead-208 (208Pb), the heaviest known ...

Neutron stars are some of the densest objects in the universe. They are the core of a collapsed megastar that went supernova, ...

Explore the surprising findings of helium presence in volcanic eruptions and its implications on geological and chemical processes deep inside the Earth.

For decades, scientists believed that lead-208 (²⁰⁸Pb), the heaviest known "doubly magic" nucleus, was perfectly spherical.

it was possible to construct a table with ascending values of atomic number, and achieve a better understanding of the table’s workings. It has also provided a guide to more-exotic forms of matter.

He is particularly interested in how nuclear structure — the organization of protons and neutrons within an atomic nucleus — evolves for exotic ... If we see it, we then know that lepton number [the ...

resulting in a new element that had 112 protons and 166 neutrons — that is, an atomic-mass number of 278. Although forcing the two nuclei (zinc and lead) together requires a considerable amount ...

The discovery suggests that atomic nuclei may be more complex ... 208 Pb is a very special atom. When the number of protons or neutrons is what we call a 'magic' number, those nucleons form ...

Despite the enormous number of neutrinos around us ... force that enables positively charged particles called protons, which make up to atomic nucleus, to change into neutrons, neutrally charged ...

Protons and neutrons stay together in the nucleus and make a stable atomic center, thanks to powerful interactions ... If the nucleus has a stable arrangement – sometimes referred to as a magic number ...

The interactions between quarks within a proton and the quarks of other protons and neutrons in atomic nuclei are notoriously difficult to fully model. To bring some clarity to the problem ...
