You know the decay mode from answer (d) which completely defines its equation. Find the box it goes to on the chart and state the name of the isotope it decays to. Remember that all decays move toward the most stable product. Use slide 16 - 18 from the April 6 lecture (on tophat) if you want a similar example to look at.5. (12 pts) Go to the website: hpszl/wwwnndcbnl.govudat2/ Find xenon (move the mouse around the upper right comer until you nd any Xe). Click on a Xe box. Then move the zoom slider on the left to zoom in or out. (a) How many stable isotopes of xenon are there? How many unstable isotopes of xenon are there? Write down the lowest and highest number of neutrons that can be found in any isotope of Xe. You can move the chart around while zoomed by clicking and dragging. (b) Name the two nearest isotones of 132Xe (c) At maximum zoom, identify the three most common isotopes of Xe and list their abundance. (d) What is the half-life of 133Xe? Mouse over the box and write down the 100% decay mode
