Nuclear Physics with Intermediate Energy Probes

一个用户模式的研究计划将主要在电磁核物理中进行，但在强子探针方面也将继续努力。活动将包括：(1)研究核子的电和磁极化率，测量δ共振d态，并在BNL的LEGS设备上使用偏振伽马射线探测氘核光衰变中的介子交换电流；(2)利用极化氘核分离离散等标量态和共振的核结构研究；(3)在土星和后来的波恩电子加速器上产生基本中性π和eta介子；(4)利用CEBAF CLAS探测器研究矢量介子的电产生和衰变。对于后一种实验，将进行数据采集和探测器控制软件的开发工作。

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.
