Nuclear Structure Theory

9312628 Draayer路易斯安那州立大学理论核物理项目由J.P.Draayer教授指导，目前涉及五名研究生(四名物理学专业和一名计算机科学专业)和一名博士后研究助理，目的是简单但准确地描述重核的性质，如由大量质子和中子(大于150)组成的稀土(如Er)和氡系(如铀)区域的性质。这些物种足够重，可以显示出与邻近元素共有的一般特征，但又显示出独特的个体特征，我们可以利用这些特征来了解质子和中子之间以及在核介质中如何相互作用。我们正在寻求以一种理智上诚实的方式回答这样的问题，例如，为什么旋转和振动模式主导着重原子核的结构？这项研究涉及对研究生进行批判性思维技能的培训，以及使用最先进的计算设施，如超级计算机(可在全国各地的中心使用)和并行机器(可通过国家8G专项资金获得)，这些将有助于定义下一代巨型计算机。7‘7 7l 7 7 7`7 7 7E 74 7 7 71 7M 7 7 7 7H 7“7”7 7 7 8ı8 U WV F F0(&amp；Z t F 1*^F&amp；Ht HH|？P=H~8 F+F t F^&amp；U=|F v/P0~u v v V 7 F P F P v V~q 2，F~t~u~@！！A(Times New Roman符号&amp；Arial“h R/Terri L.Hicks Terri L.Hicks

9312628 Draayer The aim of the program in theoretical nuclear physics at Louisiana State University, which is under the direction of Professor J.P. Draayer and currently involves five graduate students (four in physics and one in computer science) and one postdoctoral research associate, is to give a simple but accurate description of the properties of heavy nuclei, like those in the rare earth (e.g., erbium) and actinide (e.g., uranium) regions which are made up of a large number of protons plus neutrons (greater than 150). These species are heavy enough to display generic features shared with neighboring elements and yet show unique individual characteristics that we can use to learn about how protons and neutrons interact among themselves and with each other inside the nuclear medium. We are seeking to answer in an intellectually honest way questions such as, "Why do rotational and vibrational modes dominate the structure of heavy nuclei?" The research involves training of graduate students in critical thinking skills and the use of state-of-the-art computing facilities, such as supercomputers (available at centers across the country) and parallel machines (available through special "8g" state funding) that will help define the next generation of megacomputers. 7' 7 7l 7 7 7` 7 7 7E 74 7 7 7 71 7M 7 7 7 7 7 7 7H 7" 7" 7 7 7 7 8ı 8 U WV F F 0 (& Z t F 1 * ^ F & Ht HH|?p=H~ 8 F F + F t F ^ & ? u = | F F F v v v /p0 ~ u v v V 7 F P F P v v v V ~ Q 2 , F ~ t ~ t ~ t ~ u ~ @ ! !
