The energy released by the electron-capture decay is 0.835 MeV.
What is electron capture?
Electron capture is a process of electron of low energy orbital are captured by the nucleus.
Δm = m2 - m1
Δm = 56.936296 u - 56.935399 u
Δm = 0.000897 u
The energy released by the electron-capture decay
E = Δmc²
( 0.000897 u) c² ( 931. 5 MeV /c²/ 1 u)= 0.8355555 MeV
Thus, the energy released by the electron-capture decay is 0.835 MeV.
