.^(64)Cu(T_(50)=12.8h) decays beta^(-) emission (38%), beta^(+) emission (19%) and electron capture (43%). Write the decay products and calculate partial half-lives for each of the decay processes.

Answer»


Answer :`t_(1)=33.68h`
`t_(2)=67.36h`
`t_(3)=29.76h`
Where `t_(1)`, `t_(2)` and `t_(3)` are the parallel half lives for `BETA^(-)` emission , `beta^(+)` emission and electron CAPTURE processes, respectively.
