The nuclear theory program at Louisiana State University is focused on understanding the structure of atomic nuclei, from single-particle behavior that validates the use of mean-field techniques to many-particle phenomena that manifest themselves as collective rotations and vibrations in nuclei. Microscopic (shell model) and macroscopic (collective model) pictures are used to describe various phenomena. Algebraic methods that employ group theoretical techniques, and non-linear constructions that exploit coherent state theory (solitons), enter into studies of excitation spectra and electromagnetic transition rates, especially of strongly deformed nuclei. Agreement with data is the fundamental standard against which theories are tested. Successful theories are used to predict results in domains where measurements have not been made.

路易斯安那州立大学的核理论课程专注于理解原子核的结构，从验证平均场技术使用的单粒子行为到表现为集体旋转和原子核振动的多粒子现象。 微观（壳模型）和宏观（集体模型）图像被用来描述各种现象。 采用群论技术的代数方法和利用相干态理论（孤子）的非线性结构，进入激发谱和电磁跃迁率的研究，特别是强变形核。 与数据的一致性是检验理论的基本标准。 成功的理论被用来预测尚未进行测量的领域的结果。
