Radioactive Decay
β +
▪ + decay
In 89.9%:
The β + -particle and the neutrino share the disintegration energy Q β+ . The emitted β + -particle can have any kinetic energy up to the maximum possible, T β+,max , as can be derived from:
E
= Q
β+ - 1.2746 MeV*= 0.546 MeV
β+,max
*daughter nucleus is always (99.944%) in an excited state and decays via isometric transition to the ground state by emitting 1.2746 MeV γ-rays.
