Suppose a radioisotope is slightly below the blue curve in the (N vs. Z) stability diagram given in the radioactivity lecture, i.e. it has too few neutrons relative to the number of protons. However, the transformation energy by which it differs from its daughter is only 0.4 MeV. What mechanism(s) of decay can it undergo in order to move closer to the blue curve? What mechanisms are unavailable to it? Assume that Z < 50, so alpha decays are not an option.
