Photon amu
WebBarium-137m has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of 137 Cs. Barium-137m decays to the ground state by emission of photons having energy 0.6617 MeV. [8] A total of 85.1% of 137 Cs decay generates gamma ray emission in this manner. WebThe mass of the electron equal to the mass of the positron is \rm 0.000548756 \ amu 0.000548756 amu. In kilograms, the exact value of the positron mass is about \rm 9.11 \times 10^ {-31} \ kg 9.11× 10−31 kg . The positron is produced by the departing neutron in the radioactive decay and their kinetic energy is supported by the motion.
