SOLEIL’s contribution to understanding Astrophysics & Astrochemistry

More than 10 years after the opening to our users, SOLEIL takes stock of the important results obtained thanks to the beamlines during this period. Thus, we invite you to discover a series of thematic brochures presenting the major scientific contributions of Synchrotron SOLEIL to several society challenges. After the Medical Diagnosis and Prognosis, the Agro-Food sector and...

Origin of Life: the natural asymmetry of biomolecules could be due to a photophysical...

Chiral molecules exist in two forms, called enantiomers, which cannot be superimposed but are mirror images one of the other. Amino acids, the chiral elementary building blocks of proteins, only...

Condensation effects on electron chiral asymmetries in the photoionization of Serine:...

Researchers from the DESIRS beamline have determined for the first time chiral* asymmetries (caused by photoelectron circular dichroism (PECD*)) in photoelectron imaging experiments on chiral aerosol...

Ionization potential of the cyano radical and implications for CN⁺ cation...

The cyano radical (CN) is omnipresent in many reactions and environments (plasma, combustion, …). It is for instance one of the first species detected in astrophysical media such as comets (in 1881)...

Hard x rays induce a MUST ultrafast dissociation phenomenon

Interaction of light with matter is multifarious. Light can be absorbed, emitted, reflected, scattered. It can warm and cool, destroy or heal. Light, or electromagnetic radiation, of various specific...

Pulses of extreme UV radiation

Physicists have just generated ultra short polarized light pulses of extreme UV in laboratory conditions. This kind of radiation gives access to information on the chirality that would remain...

A novel flame experiment, based upon coincidence spectroscopy, demonstrates multiplex...

Lighting a candle, a quite ordinary action, starts a highly complex chemical reaction sequence: the combustion of the candle wax. The warm and festive yellow candlelight is radiated from soot...
