routine for electron - nuclei (core) interaction

Dear CP2K community,
  I need to define an unusual electron - nuclei interaction, instead of the
usual Coulomb's law. Specifically, the nuclei-electron energy of a given
electron orbital does not follow the equation:   <e|1/(R-e)|e>, where |e> is
the electron orbital and (R-e) is the vector connecting nuclei and electron.

  I am wondering what subroutines of CP2K handle the calculation of
nuclei-electron (or core-electron) energy ? Is it possible to define a new
type of such interaction in the input file without hacking the source code?

  Thanks for any advice.
