Session 10: Gravity, new measurements
- Stephan Schlamminger (NIST)
The Newtonian gravitational constant G is one of the fundamental constants of nature. Accurate knowledge of this constant is not only of considerable methodological interest, but is also important due to the key role which it plays in gravity, cosmology, geophysics. The first experiment to measure the gravitation constant with a relative uncertainty of 1% has been performed in 1798 by Henry...

One of the quantities measured with high precision in heavy atoms (and low-atomic molecules) is the hyperfine splitting constant. For the most accurate theoretical prediction of this splitting one has to take into account nuclear structure contributions. These are contributions from the distribution of the charge (Breit-Rosental effect) [1, 2] and magnetization (Bohr-Weisskopf effect) [3, 4]...
