← ScienceWhich outcome occurs when a high-energy photon interacts with a molecule forcing an electron beyond the ionization energy?
A)Auger electron emission✓
B)Vibrational mode excitation
C)Fluorescent photon emission
D)Internal conversion enhancement
💡 Explanation
When a photon's energy exceeds the ionization energy, an electron is ejected, creating a core hole, and Auger emission occurs because another electron fills this vacancy, transferring energy to a second electron which is then emitted. Therefore Auger emission results, rather than vibrational excitation, fluorescence, or internal conversion, which involve lower energy photons.
