Collect your data using either a Geiger-Müeller tube or a sodium iodide sci Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds. [4] The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively.

2010-11-01 · The currently accepted value for the half-life of 141 Ba is 18.27(7) min. Hahn and Strassmann had originally reported this half-life in barium for the first time modifying a previous observation of a single 14 min component into two components of 18 and 6 min Hahn and Strassmann also observed the relationship of the 18 min half-life with a 3.5 h component in lanthanum. BARIUM-137 isotope is used for studies of high-temperature superconductors; Barium-137 isotope is available to order from in Barium-137 carbonate (BaCO3) chemical form. Please contact us via request a Barium-137 isotope quote to order Barium-137 isotope, to get Barium-137 price and to buy Barium-137 isotope. Steve: The half-life of metastable barium-137 is listed as being 2.552 minutes, which is about 153 seconds. So, how did you do? Did you get something close to that value?

Why not? 2. You used a strontium-90 source in Part C of this experiment. Write the balanced equation showing this beta decay. 3. Use our equipment to measure the half-life of a radioactive isotope, barium-137m!

To resolve this paradox, consider an everyday analogy. An unstable nucleus in a sample of radioactive material is like a popcorn kernel in a batch of popcorn that is being heated. When a kernel pops, it changes form. Ba. Synonyms. Barium-137. Barium, isotope of mass 137. 13981-97-0.
