Positron-emitting radioisotopes of zinc that have potential applications as tools for metallomics investigations
Radio nuclide | Half-life (t1/2) | Decay modea | Mean positron energy (MeV) | Daughter nuclide | Production method |
---|---|---|---|---|---|
62Zn | 9.3 h | β+(8.2%), EC | 0.26 | 62Cub | Cyclotron: solid Cu foil target, 63Cu(p,2n)62Zn |
63Zn | 38.5 min | β+(93%), EC | 0.99 | 63Cu | Cyclotron: liquid 63Cu nitrate target, 63Cu(p,n)63Zn |
65Zn | 243.8 d | β+(98%), EC | 0.14 | 65Cu | Cyclotron: solid 65Cu target, 65Cu(p,n)65Zn |
EC denotes electron capture. a Parentheses denote percentage intensity (I). b 62Cu decays via β+ decay (t1/2 = 10 min, Iβ+ = 98%, Eβ+ = 2.91 MeV).
