    I What gives an optimum value for electron energy to ionise atom?

    I understand that we can't go back and try to understand Atoms in Newtonian terms, not that I really understand the way they do work. When the electron is part of an atom it is bound by laws beyond my understanding, but for the free electron before and after it is close to the atom it obeys...

    I What gives an optimum value for electron energy to ionise atom?

    Thanks PeroK and Bystander. It is often said that the de Broglie wavelength should be close to the physical dimensions of the structure. But thinking about the electron and atom in just a Newtonian view, and of course accepting that the electron will never make contact with another particle, it...

    I What gives an optimum value for electron energy to ionise atom?

    The question is quite simple, but I don't think I initially phrased it well. When a stream of electrons is used for ionisation, the optimum value for electron energy is normally attributed to something in the frequency domain. Question: Is it possible to visualise why there is an optimum value...

    I What gives an optimum value for electron energy to ionise atom?

    Thankyou for the reply baluncore, but it is not really what I was getting at. I am talking about using EI to ionise a sample. Thinking about the electron passing through the space ocupied by the atom as a particle: is it possible to understand the concept of the electron having a frequency that...

    I What gives an optimum value for electron energy to ionise atom?

    There is an optimum energy which gives the greatest probability of ionisation of a particular element. This is said to align with the wavelength of the electron being close to resonances in the atom. Looking at this in a different way as particles, would it be correct to say that the optimum...
