Elements of Physics Matter: Atoms and Molecules
... In 1930, James Chadwick discovered the neutron, which was found to have the same mass as the proton. With this discovery, it became clear that the mass of an atom came from the nucleus. Nuclear Shell Model This model is used to describe the behavior of electrons orbiting the nucleus of an atom. Elec ...

Vacuum Polarization and the Electric Charge of the Positron
... construct a low-energy effective theory describing particles and antiparticles with unequal opposite charges. We now apply the Lagrangian (3) to the calculation of order α(Zα)2 vacuum polarization in atoms, which is the lowest order where a nonvanishing (Qe + Qē ) would contribute. The relevant Fey ...

Coupling of Polarization and Dislocation in Ferroelectric Smectic
... large (.1 kHz) nothing happens. The ions are immobile and the screening at large distances is achieved. When the frequency is lowered and reaches 10 Hz we start to observe a distortion of the meniscus. The dislocation loops forming the meniscus change their shape with the frequency of the applied fi ...

The Ion Band State Theory Abstract
... The ion band state theory is consistent with the QEDCM17 picture of a nonperturbative ground state (NPGS). This idea, which also has been applied in the study of critical phenomena18, is based upon the notion that the ground state has preferential length scales associated with it which distinguish i ...

NUCLEAR MAGNETIC RESONANCE (NMR) SPECTROSCOPY

This magnetic shielding has the effect that a higher external field is required to meet the resonance condition in an experiment in which the field is varied, while at a constant field, B0, the resonance condition is met at a lower frequency than might be expected. In a NMR experiment, the inevitabl ...
