The possibility of positional isomer separation induced by radiation of an infrared free electron laser has been demonstrated. Experiments were carried out in 1:1 mixture of para- and meta-hexafluoroxylenes in gaseous phase. Wide tunability of free electron laser allowed for enrichment of the reaction mixture either by meta- or para-isomer. The maximum isomer selectivity achieved, defined as a ratio of dissociation yields per laser pulse of corresponding species, was higher than 300.

    A simple scaling of bulk laser-induced breakdown threshold for wide band-gap solids is derived on the basis of a recent modification of the Keldysh photo-ionization model [43, 46]. Contrary to most traditional models, the modification is based on rigorous energy dependence of reduced effective...

    In this paper we examine the behavior of small cluster of atoms in a short (10-50 fs) very intense hard X-ray (10 keV) pulse. We use numerical modeling based on the non-relativistic classical equation of motion. Quantum processes are taken into account by the respective cross-sections. We show...
