X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
