Examples
After one of these decays the resultant nucleus may be left in an excited state, and in this case it decays to its ground state by emitting high energy photons (gamma decay).
It has been reported experimentally by direct observation that the half-life of 180m Ta to gamma decay must be more than 10 15 years.
Thus, gamma decay usually follows alpha or beta decay.
