For example, CuKα X-rays are emitted from the K orbital of copper.</li> <li>X-ray <a href="/facts/Absorption_(electromagnetic_radiation)/xBYKt7yS">absorption</a> is reported as which orbital absorbed the x-ray photon. In <a href="/facts/Extended_X-ray_absorption_fine_structure/6GSpQuxv">EXAFS</a> and <a href="/facts/X-ray_magnetic_circular_dichroism/Sy39mSA3">XMCD</a> the L-edge or the L absorption edge is the point where the L orbital begins to absorb x-rays.</li> <li><a href="/facts/Auger_electron_spectroscopy/GTcxGXrA">Auger</a> peaks are identified with three orbital definitions, for example KL1L2. In this case, K represents the hole that is initially present at the core level, L1 the initial state of the electron that relaxes down into the core level hole, and L2 the initial energy state of the emitted electron.</li></ul> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Siegbahn_notation/FYk5MPEn">Siegbahn notation</a> for the names of <a href="/facts/Spectral_line/HuI4Bj5f">spectral lines</a> used in <a href="/facts/X-ray_spectroscopy/spWfPwYK">X-ray spectroscopy</a></li> <li><a href="/facts/Spectroscopic_notation/0SdYQxLy">Spectroscopic notation</a></li> <li><a href="/facts/Term_symbol/7v7IFEM4">Term symbol notation</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>R.
