The deuteron mass, m d, is then found in atomic mass units, where one atomic mass unit is defined as one-twelfth the mass of the carbon atom. In previous such mass measurements, ...

The mass standard for atoms is the carbon isotope 12 C, which by definition weighs 12 atomic mass units. "Our Penning trap apparatus called LIONTRAP is located in a superconducting magnet in nearly ...

The atomic mass is usually measured in atomic mass units (amu), where 1 amu is defined as one-twelfth of the mass of a carbon-12 atom. >Mass of Neutron = 1.008 amu ...

Then, in addition, atomic units usually leave unspecified whether or not a reduced mass is given unit value instead of the electron mass, or indeed whether other modifications have been made (see ...

Atomic Mass: The atomic mass of an atom is the sum of the protons and neutrons in its nucleus. It is expressed in atomic mass units (amu). For example, Carbon-12, ...

amu - atomic mass unit, a historic unit for atomic weight - it is based on the 1/16th part of the 16 O mass. Used in discussions, should not be used in publications. Basepeak – this is the most ...

So, now instead of carbon listed as being 12.0107 atomic mass units with a measurement uncertainty of about 0.0008, it has an official atomic weight of [12.0096; 12.0116], ...
