    • In this paper the word "molecules" is often used interchangeably with "atoms," or "atoms or molecules." However, there are specific phenomena, e.g., low-energy positron capture (Sec. II C), which involve vibrational degrees of freedom, and hence, apply to molecules only.

    • BT≈25 meV, is too small to excite any electronic degrees of freedom. The formation of Ps is also impossible if we consider molecules with ionization potentials greater than the Ps binding energy of 6.8 eV.

    • At low positron energy annihilation and emission are the only decay channels of the resonances. At higher energies positron emission accompanied by the vibrational (and then electronic) excitation of the molecule becomes possible; see Sec. III B.
