Goeppert-Mayer (unit)

Physical unit
Unit name	Goeppert-Mayer
Unit symbol	${\displaystyle \mathrm {GM} }$
Physical quantity (s)	Cross section
Formula symbol	${\displaystyle B}$
dimension	${\displaystyle {\mathsf {L^{4}\;T}}}$
In SI units	${\displaystyle \mathrm {1\,GM=10^{-50}\;{\frac {cm^{4}\cdot s}{Photon\cdot Molek{\ddot {u}}l}}} }$
Named after	Maria Goeppert-Mayer
Derived from	Centimeter , second

The Goeppert-Mayer (abbreviation: GM ) is a non- SI unit for the two-photon cross-section of a material.

${\displaystyle 1\,\mathrm {GM} =10^{-50}\,\mathrm {cm^{4}\,s\,\,Photon^{-1}\,\,Molek{\ddot {u}}l^{-1}} }$

A cross section of 1 GM means that with a photon flux of 1 photon per second and cm ² in a material with a density of 1 molecule per cm ³ one of photons is absorbed over a distance of 1 cm . ${\displaystyle 10^{50}}$

The Goeppert-Mayer is named after the physicist Maria Goeppert-Mayer , who theoretically investigated two-photon scattering in her dissertation.
