Koper-64 of 64Cu is een radioactieve isotoop van koper. De isotoop komt van nature niet op Aarde voor.
Radioactief verval
Koper-64 bezit een halveringstijd van 12,69 uur. Het grootste gedeelte (61%) vervalt naar de stabiele isotoop nikkel-64:
![{\displaystyle {{\mathrm {^{~64}_{29}Cu} }{}\mathrel {\longrightarrow } {}{\mathrm {^{~64}_{28}Ni} }{}+{}{\mathrm {e^{+}} }{}+{}{\mathrm {\nu } }{\vphantom {A}}_{\smash[{t}]{e}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/d569d55744bcb865dd9e836ce677d55b62d80217)
De vervalenergie hiervan bedraagt 652,834 keV. De rest (39%) vervalt tot de radio-isotoop zink-64:
![{\displaystyle {{\mathrm {^{~64}_{29}Cu} }{}\mathrel {\longrightarrow } {}{\mathrm {^{~64}_{30}Zn} }{}+{}{\mathrm {e^{\text{-}}} }{}+{}{\bar {\nu }}{\vphantom {A}}_{\smash[{t}]{e}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/056a257d69b89b75d1f24812046ae8cd7e1859ad)
De vervalenergie bedraagt 579,353 keV. Zink-64 vervalt zelf nog naar nikkel-64 via dubbel bètaverval.
Toepassingen
Koper-64 wordt aangewend in de nucleaire geneeskunde bij medische beeldvorming en bij de behandeling van kanker.
