State-to-state Molecular Dynamics simulations have been performed,in a wide range of temperatures and collision energies, in conjunction with new Poten-tial Energy Surfaces formulated in terms of the Improved Lennard-Jones model. Suchsimulations have been exploited to investigate the scattering of H2(and its isotopologuemolecules, D2and HD) and O2 with graphite. Impinging molecules are considered intheir ground and excited roto-vibrational levels. Selectivity and peculiarities have beenhighlighted for the scattered molecules which are of crucial importance for the rational-ization of phenomena occurring at the gas-surface interfaces and of interest in astro-chemical kinetics
In a world increasingly facing new challenges at the forefront of plasma scientific research and technological innovation, CNR and ISTP pledge progress and achieve an impact in the integration of research into societal practices and policy
