Ionic scattering factors of atoms that compose biological molecules

Laser cooling of atoms, ions, or molecules by coherent scattering

We point out a laser cooling method for atoms, molecules, or ions at low saturation and large detuning from the particles' resonances. The moving particle modifies the field inside a cavity with a time delay characteristic of the cavity linewidth, while the field acts on the particle via the light shift. The dissipative mechanism can be interpreted as Doppler cooling based on preferential scatt...

Atoms and Molecules

An atom is a system formed by a pack of electrically charged particles Q called nucleus and N identical particles of charge q − . Molecules are systems with several nuclei which may not necessarily be identical . In almost all matter, the nuclei are conglomerates of neutrons and protons and the N remaining particles are electrons. Other atomic systems will be described in the exotic atoms section.
