O QUE SIGNIFICA AUTOIONIZATION EM INGLÊS
Autoionização
A auto-ionização é um processo através do qual átomos ou moléculas emitem espontaneamente um dos elétrons do escudo, passando assim de um estado com carga Z para um estado com carga Z + 1, por exemplo, de um estado eletricamente neutro para um estado de ionização individual. Os átomos podem se auto-se quando dois ou mais elétrons de valência estão excitados ou um ou mais elétrons de casca interna estão faltando. No último caso, é chamado de efeito Auger. As moléculas, além disso, podem experimentar a autoionização vibratória. Os estados de auto-ionização geralmente são de curta duração e, portanto, podem ser descritos como ressonâncias em vez de estados ligados normais.
definição de autoionization no dicionário inglês
A definição de autoionização no dicionário é o processo em que a decomposição espontânea de átomos ou moléculas excitadas resulta em emissão de elétrons, em vez de fótons.

Springer Handbook of Atomic, Molecular, and Optical Physics
The phenomenon of autoionization, or more particularly the autoionization state
itself, is treated for the most part in this chapter as a bound state. The process is
rigorously a part of the scattering continuum (Chapt. 47), but, due mostly to the ...

Since autoionization involves a nonradiative change in energy of the core ion,

Fundamentals of Mass Spectrometry
Such autoionization is referred to as the vibrational or the rotational
autoionization. The electronic autoionization is attributed to the energy transfer
from one electron to the other electron within the degree of freedom of the
electronic motion.
Autoionization is a multichannel process. Photoionization takes place via
absorption into a discrete excited state followed by decay into an underlying
continuum. Autoionization is the most important process in molecular photon
absorption ...

into an autoionization state is in a reasonable agreement with the data available.
