Bound and resonance states of the dipole-bound anion of hydrogen cyanide HCN- are studied
using a non-adiabatic pseudopotential method and the Berggren expansion technique involving
bound states, decaying resonant states, and non-resonant scattering continuum. We devise an
algorithm to identify the resonant states in the complex energy plane. To characterize spatial
distributions of electronic wave functions, we introduce the body-fixed density and use it to assign
families of resonant…
