Every new discovery must undergo thorough scientific scrutiny before being recognized. One important step in the process is confirmation by independent experiments. The case at hand is intracavity optogalvanic spectroscopy (ICOGS), which was first published by Murnick et al. in 2008, and claimed to have the potential to revolutionize rare-isotope measurements in general and those of radiocarbon in particular. Since then, no data has been reported in any shape or form to support it. On the contrary, in spite of extensive efforts at five different sites around the world – apart from Murnick’s group at Rutgers University, Professor Meijer’s group at the Energy and Sustainability Research Institute Groningen at University of Groningen, Professor Lackner’s group at the Department of Earth and Environmental Engineering at Columbia University, our group at the Department of Physics and Astronomy at Uppsala University, and the company Planetary Emission Management Inc. – the original data still remains unconfirmed, and a number of publications have seriously questioned the scientific validity of the original report.
