One example would be to apply the method to so-called isobar nuclei — nuclei with the same total number of protons and neutrons (nucleons), but different proportions of each type, according to researchers.
Such pairs are involved when two neutrons in a higher-neutron-number “parent” nucleus transform into protons via a nuclear weak decay process to create the lower-neutron-number “daughter” — a process known as double beta decay, claimed researchers.
