The provenance of oxygen (O2) has been linked to the early Earth's atmospheric and biological evolution. A permanent rise to appreciable concentrations of O2 in the atmosphere, known as the 'Great Oxidation Event (GOE),' was estimated to have occurred at around 2.4 billion years ago. However, the cause of the GOE still remains unclear.
Dalian Coherent Light Source revealing vacuum ultraviolet photodissociation of sulfur dioxide as an important prebiotic-OThe provenance of oxygen has been linked to the early Earth's atmospheric and biological evolution. A permanent rise to appreciable concentrations of Oin the atmosphere, known as the"Great Oxidation Event ," was estimated to have occurred at around 2.4 billion years ago. However, the cause of the GOE still remains unclear.
Now, a research group led by Prof. Yuan Kaijun and Prof. Yang Xueming from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences has reported oxygen production from vacuum ultraviolet

Exploring light neutron-rich nuclei: First observation of oxygen-28The study of physical systems under extreme conditions offers valuable insights into their organization and structure. In nuclear physics, neutron-rich isotopes, especially the light ones with neutron-to-proton ratio significantly different from that of stable nuclei, provide stringent tests of modern nuclear structure theories. These isotopes exist as very short-lived resonances, decaying through spontaneous neutron emission.
