Because of his failure with New Coke, Coca-Cola Classic was born. Without the first failure, there would not have been the great success of the new campaign. You see, God can turn your failures into ultimate success. He can turn your test into a testimony; your mess into a message.
Gamma decay occurs when the nucleus undergoes an energy state change without actually changing the number or ratio of nucleons. . Technetium-99m (99mTc) is an example of such an atom. Its nucleus is the isomer of Technetium-99 (99Tc), and as an isomer, Technetium-99m rests at a higher energy state than the ground state Technetium-99.
The loss of an alpha particle or a beta particle from an unstable nucleus is often accompanied by the loss of a gamma ray. A gamma ray is a form of high-energy radiation. It is similar to an X ray but of somewhat greater energy. Some unstable nuclei can decay by the emission of gamma rays only.
