Bound-free vacuum uv emissions from rare-gas alkali ionic excimers wer
e observed by relativistic electron beam pumping of, gas mixtures of X
e or Kr with hot cesium vapor. The observed two diffuse emission bands
centered at 159 and 131 nm are assigned to be the 2 (1) Sigma(+)-->1
(1) Sigma(+) transition of (XeCs)(+) and (KrCs)(+) ionic excimers, res
pectively. (C) 1997 American Institute of Physics. [S0003-6951(97)0214
