Nuclear Physics with Intermediate Energy Probes

将开展用户模式研究计划 主要是在电磁核物理学，但与一些 在强子探测器方面也在继续努力。 的活动 内容包括：（1）核子电磁场的研究 极化率，δ共振d态的测量， 和探测氘核中的介子交换电流 在BNL的LEGS上使用偏振伽马射线的光致蜕变 （2）利用极化的核结构研究 分离离散等密度态和共振的氘核 在萨克雷的土星设施;（3）基本中性π和 土星和波恩电子的η介子产生 加速器;和未来，（4）矢量介子 使用CEBAF CLAS检测器进行电产生和衰变。 对于后者的实验，将进行开发工作 编制了关于数据采集和探测器控制的软件。

A user mode research program will be carried out principally in electromagnetic nuclear physics, but with some continued effort in hadronic probes as well. The activities will include: (1) study of the nucleon electric and magnetic polarizability, measurement of the delta resonance d-state, and probes of meson exchange currents in the deuteron photodisintegration using polarized gamma rays at BNL's LEGS facility; (2) nuclear structure studies using polarized deuterons to isolate discrete isoscalar states and resonances at Saclay's Saturne facility; (3) fundamental neutral pi and eta meson production at Saturne and later at the Bonn electron accelerator; and for the future, (4) vector meson electroproduction and decay using the CEBAF CLAS detector. For the latter experiments, development work will be carried out on the data acquisition and detector control software.
