WebAnswer (1 of 10): Atomic emission spectra originates when an electron moves from one energy level to a lower one. In that process, a photon is emitted which corresponds to … WebThe blue spectra in Figure 4e, showing STS measured on areas of our sample with (3 × 3) periodicity, show indeed a shoulder at about −200 meV (black vertical dashed line in Figure 4e). STS spectra measured on the areas with a (3 × 1) periodicity, on the other hand, do not show such feature, in good agreement with the ARPES data.

"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 … " - How atomic spectra are formed
