First-ever neutron-based nuclear reaction measurement to advance reactor design

Researchers have successfully measured a crucial nuclear reaction involved in the formation of the universe's heaviest elements. The experiment, conducted at TRIUMF in Canada, provided the first direct data on the "weak r-process" using a radioactive ion beam. This breakthrough could improve understanding of heavy element creation in extreme cosmic events and potentially advance nuclear reactor physics. The study focused on the 94Sr(α,n)97Zr reaction, using novel helium targets embedded in silicon films to replicate conditions found in extreme cosmic environments.
