Using the method of complex scaling we show that scattering resonances of \( - \Delta + V \), \( V \in L^\infty _\mathrm{{c}} ( {\mathbb {R}}^n ) \), are limits of eigenvalues of \( - \Delta + V - i \varepsilon x^2 \) as \( \varepsilon \rightarrow 0+\). That justifies a method proposed in computational chemistry and reflects a general principle for resonances in other settings.
