<p>Physics Nuclear Physics Lab</p><p>1. Visit the following URL: http://lectureonline.cl.msu.edu/~mmp/kap30/Nuclear/nuc.htm</p><p>2. The graph on the applet is the band of stability. The number of protons is graphed on the y-axis and the number of neutrons is graphed on the x-axis. </p><p>3. You can select an isotope in various ways. You can click in the band of stability or you can select an element from the column on the right.</p><p>4. On the left column are letters. Z is the number of protons, N is the number of neutrons, and A is the mass number which is the number of nucleons. </p><p>5. Select hydrogen-1. This is a stable nucleus. Add neutrons until the nuclide shown does not exist. What is the last isotope of hydrogen that exists? ______.</p><p>6. Select carbon. Which isotopes of carbon are stable?</p><p>7. Which isotope of carbon do you predict to exist in the largest abundance in the universe? What makes you pick that isotope?</p><p>8. As the atomic number of the nuclides increases what happens to the ratio of neutrons to nucleons?</p><p>9. Which odd/odd nuclei are stable? Hint: There are 5.</p><p>10. The magic numbers are 2,8,20, 28, 50, 82, and 126. Write down the nuclide notation for five stable isotopes that have magic numbers of neutrons and/or protons.</p><p>11. Choose 5 unstable nuclei. Write their nuclide notation and predict what type of decay they will undergo.</p><p>Please visit: http://www.particleadventure.org/index.html</p><p>12. Identify the three types of radiation. Explain what each type of radiation is made of.</p><p>13. What is radioactive half-life?</p><p>14. Where does the “missing mass” of a radioactive decay go?</p><p>15. What are virtual particles?</p><p>16. What is the difference between strong and weak decays? 17. What happens when matter and antimatter encounter each other?</p><p>18. What is a bubble chamber?</p><p>19. What is a Grand Unified Theory?</p><p>20. Under what conditions are the forces unified?</p><p>21. What is supersymmetry?</p><p>22. What is stringtheory?</p><p>23. How can very small dimensions exist?</p><p>24. What is dark matter?</p><p>25. How did Rutherford discover the nucleus?</p><p>26. Take the quiz on particle tracks.</p>
