A gas mixture of krypton with a hot vapor of lithium was excited to obtain two diffuse vacuum-ultraviolet emission bands centered at 147 and 149 nm. The observed emission bands are assigned to the 21Σ+→11Σ+ and 11Π→11Σ+ transitions of (KrLi)+ ionic excimer. A similar band with two peaks at 186 and 189 nm from electron-beam-pumped Xe/Li mixtures was believed to be the same transitions of (XeLi)+ excimer.
