Professor,
ReplyDeleteIs it possible for you to have office hours earlier in the day on 2/16? I would really appreciate it, it's a bit easier to show you my work in person too. I have class during your current office hours.
I can meet at 2 PM. I can also meet after 3:30 PM. Please let me know time would work for you.
DeleteI have class from 12:30 to about 4:00 pm. :) It's alright, I will try my best to be clear on the blog. Thank you.
DeleteProfessor, I have a question on one of the option in 10.4. I can't find the option that showed in your lecture slide. The closet option is out by the factor of 10.
ReplyDeleteThank you
On the slide the unit is mSv. The answers are in mSv and Sv. You may need to convert the units.

ReplyDeleteIn number 2, 232-Th's Q value is greater than Coulomb barrier. Why would 232-Th not fission?
ReplyDeleteI'm also not sure why the answer to 10.3 is 5 mSv, when lecture 10, slide 20 says 50 mSv.
DeleteI have the sane two questions.
Deletemy mistake, you clearly understand this.

ReplyDeleteDoes anyone know why the threshold energy for 17O + 219Bi = 0 in problem 4.3?
ReplyDeleteIt's because you get a negative value like -24Mev but because it's a threshold energy, it's how much energy you need to over come and if what you need is negative it just means you don't need any, so the threshold energy is therefore 0.
