Can anyone please explain me the concept of electronic, vibrational and rotational autoionization.
What I understood is, autoionization usually occurs when the ion core is rotationally or vibrationally excited so that the ion core excitation energy is larger than the binding energy of the Rydberg electron. When we think more physically, the electron might get a "kick" from the ion core which can cause it to escape from the coulomb field. Well, this is the case if the ion core is rotationally or vibrationally excited. But, what is then electronic autoionization? If the electron excitation cause the electron to escape the coulomb field, it is normal ionization, not autoionization right?
Please explain me.
