The introduction of an appropriately chosen imaginary potential in the physical asymptotic region may transform a resonance wave function into an integrable function. We examine the conditions under which this procedure and the method of exterior complex scaling become equivalent. The procedure is tested in multichannel situations describing rotational predissociation of a van der Waals complex and Stark ionization of the hydrogen atom.
