Oxford scientists detect lowest-energy neutrino-carbon interaction ever, confirming solar fusion processes.
Scientists at the University of Oxford have detected a rare interaction between solar neutrinos and carbon-13 nuclei using the SNO+ detector at SNOLAB in Ontario, marking the lowest-energy neutrino-carbon interaction ever recorded.
Over 231 days, the experiment observed 5.6 events, closely matching the expected 4.7 from solar neutrinos, using a delayed coincidence method to distinguish signals from background noise.
The deep underground location shields the detector from cosmic radiation, enabling the capture of these elusive particles.
The finding provides the first direct measurement of the reaction’s cross-section and advances understanding of stellar fusion and fundamental particle physics.
