The Ohio University lunchtime nuclear seminar meets weekly, 11:50-12:45 Wednesdays in the Roger Finlay Conference Room, to discuss interesting papers in nuclear and particle physics. All graduate students and postdocs interested in nuclear physics are welcome to attend. We like to start the talks at 11:50 sharp, so please feel free to come as early as ~11:30 for eating and socializing.
The lead coordinators for Nuclear lunch this semester are faculty members Paul King and Daniel Phillips. Other coordinators are Carl Brune, Charlotte Elster, Justin Frantz, Ken Hicks, Zach Meisel, Madappa Prakash, and Julie Roche.

- Remember that your presentation should be less than 12 slides long. The purpose of this rule is not to overly constrain you -- it's to give you a better idea of what we expect. We do not expect your talk to be the last word on the subject or a polished seminar. Your presentation is meant to raise some of the key issues, and, ideally, to initiate discussion. If you do not understand something in the paper, say so, or write down your question. We will collect the written questions, and discuss the issues raised as a group. Feel free to contact the course organizers if you have any organizational questions.
- A challenge to speakers generally is to relate your topic to the 2015 NSAC Long Range Plan.
A couple of administrative notes for Ohio University Physics and Astronomy graduate students:
- If you are an upper-level graduate student in Nuclear physics you should sign up for this activity. You do this by registering for 8501. Since 8501 is a variable credit class you should register for two credit hours of it (=1 for Wednesday lunch-time and 1 for Tuesday at 4 pm). If you give a talk or moderate this semester you will receive a grade of A for those two credits of 8501.
- If you are a first-year graduate student and you want to come to these meetings you should register for 8501 (Nuclear Seminar). If you do this you are not required to attend the regular Tuesday afternoon research seminar---although you are, of course, very welcome if you choose to come on Tuesdays at 4 pm. In consequence first years should sign up for only one credit hour of 8501. Regular attendance on Wednesdays at lunchtime will lead to you receiving a CR for that 1 credit hour.
