We shall here discuss the calculation of resonant electronic states by  means of the complex scaling method as implemented in Octopus. By  resonant states we mean metastable electronic states  on of  finite systems, such as atoms or molecules, with a characteristic energy and lifetime.  Mathematically, resonances can be defined as poles of the scattering
