Excitation of transitions of singly charged ytterbium ions terminating on levels 4f 13(2 F°7/2)5d6s(3 D) 3[L 2]°

The excitation of transitions of singly charged ytterbium ions terminating on odd levels 4f 13(2 F°7/2)5d6s(3 D) 3[L 2]° is experimentally studied. The generation of excited ytterbium ions occurs as the process of simultaneous excitation and ionization under single electron-atom collisions. Eighty five excitation cross sections are measured at an electron energy of 50 eV. Fifteen optical excitation functions are recorded with the energy of exciting electrons varying from zero to 200 eV.
