Appearance energy
From Infogalactic: the planetary knowledge core
(Redirected from Appearance potential spectroscopy)
Appearance energy (also known as appearance potential) is the minimum energy that must be supplied to a gas phase atom or molecule in order to produce an ion. In mass spectrometry, it is accounted as the voltage to correspond for electron ionization. [1] This is the minimum electron energy that produces an ion.[2] In photoionization it is the minimum photon energy.
