The model-potential approach previously developed by the authors to study positron interactions with molecules is used to calculate the positron binding energy for n-alkanes (CnH2n+2) and the corresponding cycloalkanes (CnH2n). For n-alkanes, the dependence of the binding energy on the conformation of the molecule is investigated, with more compact structures showing greater binding energies. As a result, thermally averaged binding energies for larger alkanes (n ≳ 9) show a strong temperature… 

Enhancement of positron binding energy in molecules containing π bonds

Observation of vibrational Feshbach resonances in the annihilation spectra of positrons on molecules provides a direct measurement of the positron-molecule binding energy ε B, and the relationship between the dependence ofλ B on the number of π bonds and electron-positron correlation effects (such as virtual positronium formation) is discussed.

Resonant Annihilation and Positron Bound States in Benzene.

Positrons attach to molecules in vibrationally resonant two-body collisions that result in greatly enhanced annihilation rates. Measurements of annihilation as a function of positron energy are

Positron Binding and Annihilation Properties of Amino Acid Systems

It is found that delocalization characteristics of both electrons and positrons play key roles to enhance the positron annihilation rate arising from both the valence electrons in σ- and π-type molecular orbitals from 2p atomic orbitals but not from the highest occupied molecular orbital electrons, particularly for comparatively weakly bound positronic amino acid systems.
