The interaction of low-energy scattering electrons/positrons with molecular targets characterized by a “supercritical” permanent dipole moment (≳2.0 D) presents special physical characteristics that affect their spatial distributions, around the nuclear network of the molecular partners, both above and below the energy thresholds. Such special states are described as either dipole scattering states (DSS) above thresholds or as dipole bound states (DBS) below thresholds. The details of their respective behaviour will be presented and discussed in this work in the case of the purinic DNA bases of adenine and guanine. The behavior of the additional electron, in particular, will be discussed in detail by providing new computational results that will be related to the findings from recent experiments on the same DNA bases, confirming the transient electron’s behaviour surmised by them.
This work is affectionately dedicated to Michael Allan on the occasion of his official retirement. We wish to this dear friend and outstanding scientist many years to come in the happy pursuit of his many scientific interests.
