WebFig. 1 The combined signal spectra of PSD for protons and helium nuclei. The left panel is for BGO deposited energies between 447 and 562 GeV, the middle panel is for BGO deposited energies of 4.47 to 5.62 TeV, and the right panel is for BGO deposited energies between 20 and 63 TeV. WebThere must also be space in the higher level for the electron to move into. The gaps (dark lines) in an absorption spectrum are formed because light of the specific energy (or wavelength, if you prefer) in the dark lines is absorbed by the atoms in a gas. This process is called photo-excitation.
