Excitation of transitions of singly charged ytterbium ions terminating on levels $4f^{13}(^2F^\circ_{7/2})5d6s(^3D)^3[L_2]^\circ$

The excitation of transitions of singly charged ytterbium ions terminating on odd levels $4f^{13}(^2F^\circ_{7/2})5d6s(^3D)^3[L_2]^\circ$ 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.
