Energy Levels of ThII in the range of 7 to 10 eV

Data is presented on 166 previously unknown energy levels of Th+ ions, observed using resonant two-step laser excitation of trapped ions. The levels are of even parity and within the energy range from 7.8 to 9.8 eV. Observed lines are listed. The observed levels can be relevant for the excitation or decay of the Th-229m isomeric nuclear state which lies in this energy range.
