Web12 de set. de 2024 · X-ray production provides an important test of quantum mechanics. According to the Bohr model, the energy of a Kα X-ray depends on the nuclear charge or atomic number, Z. If Z is large, Coulomb forces in the atom are large, energy differences ( ΔE) are large, and, therefore, the energy of radiated photons is large. WebLine spectra are produced when isolated atoms (e.g. in outer space or in high-vacuum tubes) emit or absorb only certain frequencies of energy (photons).
