The cis–syn cyclobutane pyrimidine dimer is one of the major classes of carcinogenic UV‐
induced DNA photoproducts. In this work, diverse high‐level quantum‐chemical methods …

We present measurements of ion-pair dissociation (IPD) of highly excited neutral and
ionized carbon clusters C n= 2− 5 (q= 0− 3)+. The tool for producing these species was a …

This article reviews previously employed methods to study several valence electronic
transitions, optically forbidden or not, enhancing intensity through vibronic coupling …

Absolute cross sections have been measured for electron-impact dissociative excitation and
ionization of the helium-hydride ion (HeH+) leading to the formation of helium ions He q+(q …

It is a difficult task to obtain “twin atoms”, ie pairs of massive particles such that one can
perform experiments in the same fashion that is routinely done with “twin photons”. One …
