This proposal will investigate the structure of atomic nuclei at the extremes of stability, angular momentum, and energy. The studies will include nuclear systems beyond the proton drip line and at thelimits of stability to fission. Techniques will be developed to study light-ion transfer reactions on nuclei far from stability using radioactive ion beams. This proposal also addresses, via measurements of magnetic moments of excited states, the the microscopic description of nuclear wavefunctions as a function of energy and spin, the study of residual nucleon-nucleon interactions, and the interplay of single particle configurations with an underlying spherical or deformed core. A new technique, combining the traditional transient field method with the newly developed approach involving Coulomb excitation of {\it beams} in inverse kinematics, will be explored in order to measure magnetic moments of excited states withsubpicosecond lifetimes in nuclei close to shell closure. The structure of the proposed activities is designed to have great impact on the education and training of graduate and undergraduate students, as well as postdoctoral associates involved with these experimental research activities.

该提案将研究原子核在稳定性、角动量和能量极端情况下的结构。 这些研究将包括超出质子滴线和裂变稳定性极限的核系统。将开发利用放射性离子束研究远离稳定的原子核上的轻离子转移反应的技术。 该提案还通过测量激发态磁矩，对核波函数作为能量和自旋函数的微观描述、残余核子-核子相互作用的研究，以及单粒子构型与底层球形或变形核的相互作用进行研究。 将探索一种新技术，将传统的瞬态场方法与新开发的涉及逆运动学中的库仑激发的方法相结合，以测量接近壳闭合的核中亚皮秒寿命的激发态磁矩。 拟议活动的结构旨在对研究生和本科生以及参与这些实验研究活动的博士后的教育和培训产生重大影响。
