I am research director at CNRS and currently works at the Institut des Sciences Moleculaires from the University of Bordeaux . I do research in Astrochemistry, and on ultra cold molecule . My most recent interest concern the formation of molecules in the gaz phase by radiative processes like radiative association for the neutral molecules and electron photo attachement for the anions. In a recent publication published in MNRAS I showed that exact quantum calculation exclude the formation of HCO by radiative association in the gaz phase. The same method was shortly after used to study the radiative association of H- and CO and to compare it to the radiative electron attachment by HCO. The later process appears to be more probable.
