We perform single-ion spectroscopy of the ²S_1/2(F=0) - ²D_3/2(F=2) clock transition at 435 nm in ¹⁷¹Yb⁺. ¹⁷¹Yb⁺ has magnetic-field insensitive transitions. We detect m_F=0 to 0 magnetic-field insensitive components. We observe that the carrier spectrum is stronger than any sidebands. This result shows a better resolution and indicates a lower temperature than those obtained in our previous report.
