The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of ...

Scientists found an unexpected nuclear energy shift in radioactive lanthanum isotopes, challenging existing models and ...

Key fact Isotopes are forms of an element that have ... neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

The chart of nuclides sorts isotopes by their proton vs. neutron numbers. This region shows newly discovered isotopes (yellow) that were produced at the Facility for Rare Isotope Beams by ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...

My current research projects involve using stable nitrogen isotopes and cosmogenic nuclides to investigate North Atlantic ice sheet dynamics and ocean biogeochemical cycling across the Pleistocene.
