Feshbach Resonances in Soft X-ray–Induced O2 Dissociation

I worked with Fellows Margaret Murnane and Henry Kapteyn from the Kepteyn-Murnane Group. I was originally creating this graphic to be published in an Science magazine article (Science 322, 1081 (2008)). Science is also making this visual available as a PowerPoint slide for teaching purposes.

The graphic explains the Photoionization. After a X-ray knocks an electron out of an O2 molecule, it takes more than 300 fs before another electron is ejected and the molecule falls apart. The internal state of the molecule prevents the second electron from being ejected until the O nuclei move at least 30 Å (3 nm) apart. Check out the Science article for the research and the JILA Light & Matter article for a more generalized explaination of the research.
