I need to read this article

"On the spectrum of an energy operator for atoms with fixed nuclei in subspaces corresponding to irriducible representations of permutation groups"

authors:G.Zhislin, A. Sigalov (Izv. Akad. Nauk. SSSR Ser. Mat. 1965 29 pagg 853-860)

but I've found it in Russian only. Is there anyone who knows the existence of a translation of this article?

Izv. Akad. Nauk.started being translated into English in 1967 -- two years too late for the OP's request. $\endgroup$ – Barry Cipra Mar 14 '13 at 16:40
