Research in Low Energy Nuclear Physics

低能核物理研究一个基础广泛的计划，提出了使用斯托尼布鲁克超导直线加速器以及其他地方的最先进的设施，如伽玛射线管研究核和原子的性质。 该计划强调核结构物理学的前沿问题（平滑带终止，A= 3D 100附近的质子滴线附近的物理，M1激发，A= 3D 80区域的超变形和其他大变形形状，以及粒子和伽马射线发射之间的竞争）。 另一个研究领域利用巨共振的衰变来研究核物质的性质（核耗散、超导到液滴相变、核可压缩性作为温度的函数）。该计划的另一个组成部分建议继续准备测试电弱相互作用（Fr原子的宇称不守恒）。 将准备一个更合适的Francium实验室，以便进行高精度的原子物理测量（斯塔克诱导的7s -8 s跃迁和超精细异常测量）。 斯托尼布鲁克核结构实验室也是许多教育活动的重点。高中，本科，研究生和博士后水平的学生参加各种强度的研究计划，从光束线建设到运行实际实验。

Research in Low Energy Nuclear Physics A broadly based program is proposed to study properties of nuclei and atoms using the Stony Brook superconducting linac as well as state of the art facilities available elsewhere such as Gammasphere. The program emphasizes frontier issues in nuclear structure physics (smooth band termination, physics near the proton drip line near A=3D100, M1 excitations, superdeformed and other large deformation shapes in the A=3D80 region, and the competition between particle and gamma-ray emission at the limits of stability). Another venue of research utilizes the decay of giant resonances to study properties of nuclear matter (nuclear dissipation, superconducting-to-liquid drop phase transition, nu-clear compressibility as a function of temperature). Another component of the program proposes to continue preparations for a test of the electroweak interaction (parity non-conservation in Fr atoms). A more suitable Francium laboratory will be prepared in order to perform atomic physics measurements with great accuracy (Stark-induced 7s -- 8s transition and hyperfine anomaly measurements). The Stony Brook Nuclear Structure Laboratory also serves as a focus of many educational activities. Students at the high school, undergraduate, graduate, and postdoctoral levels participate in the research program with various intensities, from beam line construction to running actual experiments.
