and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

An unknown 'bump' on a scientist's screen In this work, researchers determined two-neutron separation energies of the lanthanum isotopes and discovered a strong, local increase, a "bump," in the ...

The least abundant tantalum isotope, Ta-180 is found naturally in ... In this project, physicists restructured the MAJORANA ultra-low background facility at the Sanford Underground Research ...

Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium ...

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 ...
