WebThe most common decay mode of a radioisotope of zinc with a mass number lower than 66 is electron capture. The decay product resulting from electron capture is an isotope of copper. n 30 Zn + e − → n 29 Cu. The most common decay mode of a radioisotope of zinc with mass number higher than 66 is beta decay (β −), which produces an isotope ...
