The physical relevance of the resonance wave function is discussed in view of the complex scaling theory. It is argued that although it is unphysical in the sense that it corresponds to a complex energy it is useful when we want to understand and compute several physical observables. We first review our work on the influence of resonances on a scattering cross sections. We then discuss the partial widths concept as presented by Peshkin, Moiseyev and Lefebvre [J. Chem. Phys. 92 2902 (1990)]. Finally we use this formalism to suggest a way to define a root mean square radius of a resonant state.
