22.02  Intro to Applied Nuclear Physics

Dear class,

Wish you all the best for the 22.02 final exam!

Dear Class,

Pset 9 has been graded already. For electronic submissions, please find it in your pset sharing folder; for hard-copies, you'll have them in next class. Important reminder, the pset sharing folder will expire one week from now (May 17th, 2015), so please download and keep your own copy for future record. 

A few comments related to commonly-met mistakes in pset 9:

Problem 3
Plot question. The kinetic energy of bneta-decayed electrons, T, has finite range due to physics. T is kinetic energy, so T>0, and T is partitioned from Q value, so T<0.5MeV. It is uncessary to plot other unphysical region or imaginary part. However, there is no point deducted.

Problem 4
There is one possibility that final spin If = Ii -1. However, If Ii = 1/2, Since If >0, the possibility for If = Ii-1 is ruled out as a special case. Please be aware of this case but no point is deducted.

We wish you all the best for the final exam preparation, and please don't hesitate to let me know for any questions related to final exam.

Dear Class,

For the convenience of your final exam preparation, pset 9 solution is now uploaded to Stellar. Since we already have 2 recitations for final exam review, there is no upcoming recitation next week. But please don't hesitate at all to let me know if you are meeting any diffuculties or having any questions during your review progress, and I'll response to you the same day you'd ask.

Wish you all the best for the final exam, and future semesters. 

Dear Class,

On this Tue and Fri we'll have 2 recitation sessions focusing on final exam preparation.

Best,

Dear Class,

Pset 8 has been graded. It is done remarkly well, indicating that you've already grasped the rule of thumb to determine gamma decay type from nuclear spin-parity. One thing worth mentioning is Problem 2, a nuclear energy level digram and nucleon filling drawing never hurts.
