An unresolved system of bands of the transition ιΣ*(0+}*ί1,*φ+) of the Ar2 molecule was observed for the first time in the emission spectrum of a supersonic argon jet excited by an electron beam, on the long-wave side of the λ=1048 k(}Pi-S0) resonance line. It is shown that the main contribution to the population of the 'Σ+(0+) state is made by electron interactions with diatomic and polymer argon molecules.
