Spectral lines are the result of interaction between a quantum system (usually atoms, but sometimes molecules or atomic nuclei) and a single photon. When a photon has about the right amount of energy (which is connected to its frequency) to allow a change in the energy state of the system (in the case of an atom this is usually an electron changing orbitals), the photon is absorbed. The… NettetThe Cu 2p core level spectrum ( Fig. 19.1 ), located at a binding energy (BE) of 932.9 ± 0.1 eV, does not present any satellite at higher binding energy, which proves the absence of Cu 2+ in the outermost layers [ 7 ]. The spectra indicate the presence of an ultra-thin layer of Cu 2 O on Cu. property for sale in alicante near beach
