Energy and lifetime of resonant states with real basis sets

Abstract

Using a probabilistic interpretation of resonant states, we propose a formula useful to calculate the lifetime of a resonance using square-integrable real basis-set expansion techniques. Our approach does not require an estimation of the density of states. The method is illustrated with calculations of $s$ and $p$ resonant-state energies and lifetimes.
