When the 137mBa decays into the ground state of 137Ba, it emits a gamma ray Barium-137 | Ba | CID 6335817 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety The isogenerator contains cesium-137, which decays to barium-137. The newly made barium nucleus is initially in a long-lived “excited” state, which eventually decays by emitting a gamma photon ( γ). A gamma photon is a high energy x-ray photon. The “relaxed” barium nucleus is then stable, and does not emit further radiation. Using a It happens that in the beta decay of 137 Cs, the product (or "daughter") barium nucleus is left in an "excited" state. This decays in a few minutes back to the "ground" state of the barium nucleus, emitting a photon (a quantum of light) of fairly high energy, called a "gamma" ray (technically, g amma rays of energy 0.66 MeV, corresponding to (a) Complete this decay equation for the radioactive decay of caesium -137 (Cs 137) to barium 137 (Ba-137) (b) Caesium exists in a number of different isotopes. Give the number of protons and neutrons in these two common caesium isotopes: Using the graph below, show that the half-life of Cs-137 is 34 years.

B. The nuclide cesium-137 undergoes beta decay to form barium-137 C. Th | Science Chemistry Radioactive decay 2009-03-16 · In other words, it undergoes a beta-decay. When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its atomic mass to remain the same. Atomic number of cesium is 55, so the new atomic number 56 belongs to barium.

The nuclear symbol for a β particle is #color(white)(l)_text(-1)^0"e"#. In any nuclear equation, the sum of the subscripts (atomic numbers, #"Z"#) and the sum of the superscripts (atomic masses, #"M"#) must be equal on each side of the equation.
