The likely role of atmospheric atomic oxygen in the recession of spacecraft surfaces and in the shuttle glow has revived interest in the accurate measurement of atomic oxygen densities in the upper atmosphere. The Air Force Geophysics Laboratory is supplying a quadrupole mass spectrometer for a mater...
oxygen, which was replaced in 1961. However, some sources still use the amu but now define it in the same way as u (based on carbon-12). In this sense, most uses of atomic mass units or amu today actually refer to unified atomic mass units or u. For standardization a specific atomic...
This is the unified mass unit u and is defined on the basis that the mass of the carbon nuclide C-12 is exactly 12 u [the unified mass unit supersedes the previous unit of atomic mass unit based on the mass of oxygen 0-16 being 16 amu]. From this definition: 1u=1.6604×10−27...
Before 1961 there were two definitions for atomic mass unit. The elements defined the atomic mass unit as '1/16th of the atomic weight of oxygen'. Apart from the fact that the term mass should have been used instead of weight, this definition does not specify which oxygen isotope, and imp...
