New theoretical ideas and advancements in computer technology have created a Renaissance in microscopic nuclear structure theory. More and more nuclear-theory groups are turning to the problem of how to calculate the structure of finite nuclei microscopically, mainly in terms of extremely large model spaces. Our research group was one of the first to become involved in this renewed interest in microscopic nuclear-structure calculations, our approach being one of constructing the best possible interaction to employ in the chosen model space. This has led us to work in a large model space, in which all the nuclear particles (i.e., nucleons) are active. So far this approach has been extremely successful in describing microscopically the properties of nuclei with two to ten nucleons. We plan to extend this approach to nuclei with up to 16 nucleons or even larger. Extremely large nuclei with more than 100 nucleons, which cannot be investigated by the above approach, will be studied using a model in terms of pairs of nucleons, instead of individual nucleons.

新的理论思想和计算机技术的进步创造了微观核结构理论的复兴。 越来越多的原子核理论小组开始研究如何在微观上计算有限原子核的结构，主要是在极大的模型空间中。 我们的研究小组是第一批参与这种对微观核结构计算的新兴趣的研究小组之一，我们的方法是构建最好的相互作用，以便在选定的模型空间中使用。 这使得我们在一个大的模型空间中工作，在这个空间中，所有的核粒子（即， 核是活跃的。 到目前为止，这种方法在微观上描述具有2到10个核子的原子核的性质方面非常成功。 我们计划将这种方法扩展到具有多达16个核子甚至更大的原子核。 超过100个核子的超大核，不能用上述方法进行研究，将使用核子对而不是单个核子的模型进行研究。
