Electron capture is usually followed by the emission of an \(\mathrm{x}\) ray. Why?

The following two questions concern an uncommon nuclear decay mode known as electron capture. Certain nuclei that are proton-rich but energetically prohibited from undergoing beta-plus decay can capture an electron from the \(1 s\) shell, which then combines with a proton to make a neutron. The basic reaction is
