Assigned: 16-Feb-19
1st Due Date: 21-Feb-19
2nd Due Date: 24-Feb-19
Topics:
Lecture 6: Gamma Decay
Lecture 7: Fission
Lecture 8: Nuclear Force and Nuclear
Structure
Lecture 9: Nuclear Reactions
Lecture 10: Radiation
Interactions
Use lecture notes, textbooks, Chart of the Nuclides, Table of the
Isotopes, and web pages. Use the chart
of the nuclides as your primary dataset for isotope half-life. For the 2nd submission show your
work and references on a separate page. Please use 3 significant digits for your
answers.
Here's a possible question from lecture 7:
ReplyDeleteAs the mass of the fissioning nucleus increases, what happens to the mass of the light fragment? What about the heavy fragment?
How is this reflected in fragments from the fissioning of particularly heavy isotopes, such as 258Fm?
Awesome! Let's make this a question.
DeleteI noticed that the assignment date for exam 2 was yesterday but the exam form is not made available yet on the syllabus page on canvas, and I also cant find it under File. Where can I locate the exam pdf?
ReplyDeleteThe exam was posted at 1130 on Saturday 16 February. If you cannot obtain the exam please let me know. The exam can be found at:

Hello Ken, I can't access to Exam 2 on canvas page as well
DeleteKen, for the irradiation calculation for problem 7 (part 3), would the formula be found in lecture 10 under the dosimetry section?
ReplyDeleteQuestion 7.3 is actually related to the produced isotope. Lecture 9, page 11 describes excitation functions. Based on the particle energy, a primary reaction product can be identified. This resulting isotope may be identified through gamma decay. You can review the gamma decay chapter to assist with correlating gamma emission energies with specific isotopes.

ReplyDeleteokay!
DeleteWill there be another webinar tomorrow for the exam?
ReplyDeletesure, when would be a suitable webinar time? I propose anytime after 4 PM.
Delete7pm is good, per your E-mail!
DeleteCanvas conference for Exam 2 on Thursday 21 February, either 4 PM or 7 PM. The default time is 7 PM. If enough people want 4 PM we can switch. Provide your input below. The time will be announced later tonight.
ReplyDeleteSubmitted Exam 2.
ReplyDeleteExam 2 submitted
ReplyDeleteTwo more quick questions: for the hot atom chemistry, is the secondary isotope the obvious answer (given the circumstance)? And secondly, is 2.3.3, what lecture series should I refer to.
ReplyDeleteI have turned over my celebration of learning on both canvas and email. Yay! Learning!

ReplyDeleteWhew, exam submitted.
ReplyDeleteSubmitted last night, forgot to blog
ReplyDeleteResubmitted the exam with comments in yellow for sources and such!
ReplyDeletesubmitted last night around 8pm and forgot to comment!
ReplyDeleteThanks for the quizzes and comments. If blog posts are late that is fine. As you can tell I sometimes even forget to post the blog (see Np lecture!).

ReplyDeleteResubmitted the test corrections (via canvas) for this celebration of knowledge!
ReplyDeleteI'm satisfied with my first submitted answers, so I'm not sure if I still need to resubmit the same thing?
ReplyDeleteI resubmitted the exam via Canvas and email. My corrected answers will have a checkmark stamp next to them, and the corresponding work/explanations are included in a separate pdf.
ReplyDeleteAlso, I realized today that I accidentally uploaded the wrong file on Canvas for my first submission. I'm really sorry if that caused any inconvenience or confusion. I did submit the exam by email also, so there should be proof that I completed the exam by the due date at least.
