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 emission of gamma rays does not alter the number of protons or neutrons in the nucleus but instead has the effect of moving the nucleus from a higher to a lower energy state (unstable to stable). Gamma ray emission frequently follows beta decay, alpha decay, and other nuclear decay processes. Positron emission involves a particle that has the same mass as an electron but a positive charge. The particle is released from the nucleus when a proton splits into a neutron and positive electron.
