Norman Campbell discusses the problem of the possible consistency of the assumptions about the motion and arrangement of electrons in the atom underlying ... theory of atomic structure, and ...

The Atomic Mass Data Center and its electronic bulletin are tools for the exchange of information on experimental masses, evaluation of masses, extrapolation of masses, and theoretical masses. One of ...

Historically, the vast majority of pharmaceutical drugs have been meticulously designed down to the atomic level. The ...

The European Space Agency has launched two atomic clocks on a SpaceX rocket to the ISS to test Einstein's theory of ...

equivalent to the positive charge of the atom) was less than the atomic mass (average mass of the atom). For example, a helium atom has an atomic mass of 4, but an atomic number (or positive ...

This is important because the neutrino, as the most abundant particle in the universe, "weaves a thread that connects the ...

However, the investigation, which involved high-precision measurements of shifts in ytterbium’s energy levels and the mass ratios of its isotopes, could help us better understand the structure of ...

or when atomic resolution is discussed. The power of this technique is that it is possible to determine local physical properties directly from measurements of shifts of the individual atom positions.
