Abstract

The Feshbach-type idempotent-projection procedure, developed recently by the author, is applied to closed-channel resonances of

{He}^{-}

. The energies of the well-known two

{}^{2}S

, two

{}^{2}P^{o}

, and one

{}^{2}D

resonances lying below the 3

{}^{3}S

threshold are obtained. Quartet QHQ spectra of the same symmetries are investigated, and one

{}^{4}P^{o}

autoionizing resonance below the 3

{}^{3}S

threshold is found.
