This would release .0008737 amu of mass. It is an electron capture event. This decay occurs with a half-life of 35 days.

*Q: If neutrons weigh more than protons, why does a beta-plus event that turns a neutron into a proton ''increase'' the mass, and hence the energy?
+
*A: There is a contribution to the nuclear mass from the electric repulsion force of the protons. Adding a proton increases that repulsion. This, by the way, is why elements other than the very lightest have more neutrons than protons.
