A major challenge in contemporary electronic structure theory involves the development of
methods to describe in a balanced manner the contribution of correlation effects to energy …

We performed a computational study of positron attachment to hydrated amino acids,
namely glycine, alanine, and proline in the zwitterionic form. We combined the sequential …

Certain atoms, molecules, and clusters can bind an excess electron or positron in a diffuse
orbital. Given the weak binding energy of these states, usually on the order of tens to …

The positron is the antiparticle of the electron, possesing the same mass and obeying the
same spin statistics but with an opposite charge. When a positron and an electron collide …
