In summary, the fine structure of X-Ray transition is primarily caused by the scattering of the photoelectron by neighboring atoms after the removal of a core electron. This is evident in the sample of X-ray lines in molybdenum between 0.5 and 0.6 Angstroms, which is taken from the NIST table on atomic transition energies. Fine structure can also be split by the ionization state of the atom, with the example shown in the conversation being the 3p3/2 and 3p1/2 to 1s1/2 transitions in Mo LXII and Mo LXI. Further exploration can reveal more ionization states.

Hi,
Fine structure (oscillations) primarily arises from the fact that the photoelectron (as a result of the core electron removal) gets scattered by all neighboring atoms.

Here (in thumbnail) is a sample of X-ray lines in molybdenum between 0.5 and 0.6 Angstroms (24 KeV to 21 KeV).. This is taken from the NIST table on atomic transition energies.

There are two ways a particular atomic transition can be split:
1) Fine structure. I have drawn a box around the 3p3/2 and 3p1/2 to the 1s1/2 transitions. These are split by j = l + 1/2 and j = l - 1/2 fine structure in the 3p initial state; about 44 eV energy difference out of 21,800 eV.
2) The ionization state of atom. This table shows only two ionization states (# of electrons missing), Mo LXII and Mo LXI (LXI and LXII represent the ionization state), but there are many more. Go explore.

Related to Fine structure of X-Ray transition
1. What is the fine structure of X-Ray transition?
The fine structure of X-Ray transition refers to the splitting of spectral lines in the X-Ray region of the electromagnetic spectrum. It is caused by the interaction between the spin and orbital angular momentum of the electrons in an atom.
2. How is the fine structure of X-Ray transition measured?
The fine structure of X-Ray transition is measured using X-Ray spectroscopy techniques, such as X-Ray fluorescence spectroscopy or X-Ray absorption spectroscopy. These techniques involve bombarding a sample with X-Rays and analyzing the resulting spectrum to determine the fine structure.
3. What is the significance of studying the fine structure of X-Ray transition?
Studying the fine structure of X-Ray transition allows us to gain a better understanding of the electronic structure and behavior of atoms. It also has practical applications in fields such as material science, chemistry, and medicine.
4. Can the fine structure of X-Ray transition be affected by external factors?
Yes, the fine structure of X-Ray transition can be affected by factors such as temperature, pressure, and the chemical environment of the atom. These factors can alter the energy levels of the electrons and cause changes in the fine structure.
5. How does the fine structure of X-Ray transition differ from other types of spectroscopy?
The fine structure of X-Ray transition differs from other types of spectroscopy, such as visible light spectroscopy, in that it involves higher energy X-Rays and probes the inner electron orbitals of atoms. This allows for more precise studies of electronic structure and behavior at the atomic level.
