Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
Femtometer
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
