15. Usage: Nuclear Physics Course NaI and DAQ Layout –Week One NaI Response Function NIM & CAMAC Module discussion –Week Two “Oops, someone broke in and dismantled all the equipment”

16. Usage: Nuclear Physics Course HpGe Detector – 152 Eu Spectrum Odd-odd nucleus: 2-mode decay Practice using “Table of Isotopes” –Fiestaware Plate – 238 U decay scheme Practice using “Wall Chart” and “Table of Isotopes” Reasons behind  vs  vs  decay Data for later HW on  particle penetrabilities

17. Usage: Nuclear Physics Course Accelerator Operations –Students learn to drive –Experience with ion optics

18. Usage: Nuclear Physics Course

20. Optimum Number of Students = 2 Jobs –Driver –Data acquisition –Analysis 1 experiment can be run all day MUST review whole experiment next day in class

21. Usage: Nuclear Physics Course Gleanings –mix practical skills & book smarts –2 students per lab class (maybe 3) –Divide jobs, promote independent/team work –“You found it, You fix it” –Problems are educational experiences too –2 instructors per lab

24. Usage: Nuclear Physics Course Coulomb Excitation p + 181 Ta –“determine nuclear shape: Q” –energy loss by projectiles dE/dx –detector efficiency, solid angles,… –approximations 181Ta is not even-even Use proton xs instead of  production xs Ignore angular dependance p 181 Ta

25. p measure  at 90 o 181 Ta 7/2 + 181 Ta L=2

26. expt’l values = 6 - 9 b evaluated Q = 3.3 b
