Summer 2015: Lecture 1. Introduction and using the chart of the nuclides

The class outcomes, expectations, and grading are explained.  Resources for the course are provided, including the chart of the nuclides and links to the table of the isotopes, programs, and databases. The laboratory courses and research expectations are introduced.  A history of radioelement discovery and radiation research is presented. The Chart of the Nuclides is discussed and used. Atomic properties, nuclear nomenclature, X-rays, types of decays and physical forces are introduced.

    This lecture was very interesting due to the history of discovery in radiochemistry. It is very cool to see how this discipline has evolved over the years.

    Interesting lecture, for me it was easier to stay focused watching it at 1.5x speed.

    Great to learn about the chart of the nucleotides, and the "Nobel" families of the Curies.

    One of your study questions for this lecture asks, "What are some commonalities in the discovery of the actinides?" Could you please elaborate on this question or provide some insight on what you would look for in a response?

      for example, the new actinides were used as targets to make even heavier actinides. The reactions were 4He,xn with different target material. Ion exchange was used to isolate the actinides. The Z could be identified by the elution profile. The actinides were identified by alpha decay for the most part, beta for Bk.

      These would be some examples.

    I submitted the quiz with no problems! I just used the PDF instead of the video as the website was not letting me access the videos at the time.

    I enjoyed the overview of the history of radiochemistry. Also, I've never encountered the chart of nuclides, but when listening to your lecture online, I found it easy to comprehend and follow and use on my own. I also submitted the quiz with no problems.

      now you have your own copy of the chart. you will grow more familiar with it during the course.

    POP QUIZ: 10 facts about Pu239
    1) the spin and parity is 1/+
    2) the 1/2 life is 2.410E4 a which is about 24,100 years
    3) it has an alpha mode of decay which is 5.4992, 5.4565,....
    4) has one isometric state
    5) it is an unstable radioactive isotope
    6) parent isotopes at Cm 239, Am 239, Np 239
    7) isotopic mass is 239.052163
    8) mass number is 239
    9) the gamma mode of decay is 51.6 e-, 30.1 - 1057.3
    10) the thermal neutron capture cross section is 271, 20E1 or 750, 30E1

    I tried to understand as much as I could about Pu 239 from just studying the chart of nuclides but the chart is still a little confusing to me.

      the spin is 1/2, with + parity

      Thank you i was trying to get that across with the / in between but I can see how it's confusing

    As a Nuc student you would think I would have had a ton of experience with the chart of nuclides by this point. Sadly as a transfer student they opted me out of the intro course which also happened to be the only one that taught how to use the chart! While teaching myself how to use it has worked for me so far, I've enjoyed going through it all again through the lecture.

      I hope you will get all you can from the chart of the nuclides during the summer school.
