Friedrich Paschen
Louis Carl Heinrich Friedrich Paschen (22 January 1865 – 25 February 1947) was a German physicist, known for his work on electrical discharges. He is also known for the Paschen series, a series of hydrogen spectral lines in the infrared region ...

Paschen (crater)
Paschen is a Lunar craters, lunar impact crater on the Far side (Moon), far side of the Moon. The relatively large satellite crater Paschen M partly overlies the southern rim of Paschen, and they nearly form a merged pair with only a section of ir ...

Paschen-Back effect
The Zeeman effect () is the splitting of a spectral line into several components in the presence of a static magnetic field. It is caused by the interaction of the magnetic field with the magnetic moment of the atomic electron associated with ...
, the splitting of atomic energy levels in the presence of a strong magnetic field
** Paschen series, a
Hydrogen spectral series
The emission spectrum of atomic hydrogen has been divided into a number of ''spectral series'', with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels i ...

Paschen's law
Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. It is named after Friedrich Paschen who ...
