TRIUMF helps provide IAEA with evaluation of beta-delayed neutron emitters
In a coordinated research project under the auspices of the International Atomic Energy Agency (IAEA), Canadian researchers from TRIUMF and McMaster University have evaluated all existing beta-delayed neutron emitters and provided recommended values for their decay half-lives and neutron-branching ratios. These new recommendations, released as an IAEA report, together with the new data from ongoing experiments, will be integral part of a newly created database. Among a variety of applications, the data will be a key input in astrophysical studies for a better understanding of the heavy element production in explosive stellar events including core-collapse supernovae and binary neutron star mergers. Such a reliable and regularly updated database is essential for a better understanding of these important physical properties, especially for benchmarking theoretical predictions of yet unmeasured nuclei.
