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 ...

Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic ... trap mass spectrometer. The masses for the two most exotic isotopes, lanthanum ...

Their research teams carried out high-precision measurements of atomic transition frequencies and isotope mass ratios of ytterbium isotopes. Linear high-frequency ion traps and ultra-stable laser ...

but it was only on his release from war-service that the mass-spectrograph took on a material shape, and led to a new form of chemistry in which isotopes have taken the place of elements ...

The International Atomic Energy Agency (IAEA) defines uranium as a Low Specific Activity material. In its natural state, it consists of three isotopes (U-234 ... The specific activity is the activity ...

dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes). There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing ...

The term ‘weighted mean mass’ takes into account the different contribution of each isotope to the overall mass. Relative atomic mass is not the same as mass number. Mass numbers close mass ...

Stable isotopes can also be used as tracers, which are deliberately added to a system that is to be studied, such as in agriculture or nutrition. For this purpose, they must be separated using highly ...
