Cross-sections of electron-impact excitation of a molybdenum atom from the ground state

Electron-impact excitation of spectral lines of MoII has been investigated by the method of crossing beams. The absolute values of excitation cross sections for 30 lines of MoII in the spectral region 200-300 nm have been measured, when the energy of exciting electrons varied from 250 eV to the excitation theshold. The optical excitation function has been registered for 4 lines
