Question

This question does have multiple parts, but just answer as many as you are comfortable with. I'll give a good rating to the best answer.

Consider the imaginary element Nn with at least two electrons in all its shells. The ionization energies of those shells are for K, 10.0 KeV, for L, 3 KeV and for M, 1 KeV.

Which shells will be ionized by a 20 KeV electron, a 5 KeV electron and a 2 KeV electron?

What is the energy of K alpha, K beta and L alpha x-rays if emitted?

Which x-rays will be emitted for 20 KeV, 5 KeV or 2 KeV incident electron energies?

What are the energies of the KLL, KLM and LMM Auger electron transitions?

Which Auger electrons will be emitted 20 KeV, 5 KeV or 2 KeV incident electron energies?

Imagine the sample is struck by a 2 KeV photon. From what shells can photoelectrons be emitted and at what energies?

Imagine the same experiment but with the M ionization energy shifted to 1.1 KeV where will the XPS peak appear in an emitted electron energy spectrum and how will that compare to the answer to question above?

Explanation / Answer

To be ionized , Ionization enthalpy >= Threshold energy

So,K, L,M be ionized by 5KeV,2KeV for K :  ionized by 5KeV,2KeV

for L :  ionized by 2KeV &  for M : Won't ionized
