"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. " - How atomic spectra are formed

WebContinuous spectra (absorption or emission) are produced when (1) energy levels are not quantized, but continuous, or (2) when zillions of energy levels are so close they are essentially continuous. The first occurs, for example, in plasmas like the Sun, where the temperatures are so high that the electrons are free to travel in straight lines until they …
