Question

Discrete electrons cannot be observed in electron ionization of an atom due to which of the following reasons?

(a) Environmental disturbances

(b) Same mass

(c) Same charge

(d) Electron- electron interaction

The question was posed to me in my homework.

The question is from Electron Spectroscopy for Chemical Analysis topic in section Electron and Ion Spectrometers of Analytical Instrumentation

Answer 1

The correct option is (d) Electron- electron interaction

For explanation I would say: Discrete electrons cannot be observed in electron ionization of an atom because of electron-electron interaction. Therefore, ESCA cannot be observed when using electron ionization.
