Abstract
The stabilization method has been used by many researchers for computing energies and, in some cases, widths of metastable states arising in electron–atom and electron–molecule interactions. In the present work, the stabilization technique is exploited in a manner which makes a close connection with the so‐called complex corrdinate rotation method. The primary result is an expression which permits the resonance lifetimes to be computed directly ’’on the back of an envelope’’ from the stabilization graph which is obtained in all stabilization calculations. Several illustrative calculational results are presented.(AIP)
