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.
