Atoms are the building blocks of all matter, from the air we breathe to every cell in our bodies. Yet despite their presence everywhere, no one has truly seen an atom with the naked eye ,until ...

An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 (²⁰⁸Pb) is ...

Some history on models of the atomic nucleus Credit: C&EN I read with great interest the article by Katherine Bourzac “Divining the Mysteries of the Atomic Nucleus” in the Jan. 29, 2024, issue ...

Sep. 4, 2024 — Nuclear clocks would measure time based on changes inside an atom's nucleus, which would make them less sensitive to external disturbances and potentially more accurate than ...

In the earliest attempts at this model, scientists took their inspiration from the solar system, which has a dense "nucleus" (the sun) surrounded by a "cloud" of smaller particles (the planets ...

A nuclear isomer is an atom whose nucleus is in a higher energy state than its ground state. This excited state is very long-lived compared with the usual lifetimes of excited nuclear states.

The Science. A team of theorists has extended their previous critical analysis of the Lead Radius Experiment (PREX). The experiment involved deducing the neutron size of a lead atom’s nucleus by ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

Scientists are using trapped ions in cutting-edge experiments to hunt for signs of an undiscovered particle that might help ...

This atomic nucleus is to be used as the timekeeping element of nuclear clocks in the future. ... Sep. 4, 2024 — Nuclear clocks would measure time based on changes inside an atom's nucleus, ...

New research from Professor Guillermo Ameer’s team shows how a shape change of a cell’s nucleus can trigger regenerative ...

A nuclear clock would be based on the atom’s nucleus. Some scientists believe nuclear clocks could be even more precise than atomic clocks, which are already such powerful tools that they’re ...
