Triatomic ionic excimers have now been observed. Alkali rare-gas triatomic ionic molecules have been produced by electron beam excitation. Emission spectra centered at {approximately}159 nm due to Kr{sub 2}{sup +}Cs radiative decay were recorded. Lifetime and binding energy of the lowest excited state are estimated; the ground state is repulsive. Two formation channels for these triatomic ions are proposed and their rate coefficients estimated. {copyright} {ital 1997 American Institute of Physics.}
