Deep survey of millimeter radio recombination lines toward the planetary nebulae IC 418 and NGC 7027
Context. The circumstellar environments of planetary nebulae (PNe) are remarkably chemically rich astrophysical laboratories, proving useful for studies of the ionization of atoms and the formation of simple and complex molecules. The new generation of high-sensitivity receivers opens up the possibility to carry out the deep observations needed to
