Neon, Argon, Krypton and Xenon

Noble gases are usually only observed when they have been implanted in materials - such as when sputtering using an ion beam.  Relevant binding energies below [1].

Ne 1s: 861.6 - 863.4 eV
Ne 2s: ~ 41 eV

Ar 2p3/2: 240.3 - 241.9 eV
Ar 2p3/2 - 2p1/2 splitting is 2.12 eV
Ar 2s: ~ 320 eV
Ar 3s: ~ 24 eV

Kr 3d5/2: ~ 87 eV
Kr 3d5/2-3d3/2 splitting is 1.23 eV
Kr 3p3/2: ~ 208 eV
Kr 3p1/2: ~ 216 eV
Kr 4s: ~ 21 eV

Xe 3d5/2: 668.9 - 674.1 eV
Xe 3d5/2 - 3d3/2 splitting is 12.67 eV
Xe 3p3/2: ~ 943 eV
Xe 3p1/2: ~ 996 eV
Note that MNN Auger structure overlaps the 3p3/2 peak (when using an Al X-ray source)
Xe 4d 5/2: ~ 61 eV
Xe 4d 3/2: ~ 63 eV
Xe 4p: ~ 139 eV
Xe 4s: ~ 207 eV
Xe 3s: ~ 1141 eV
