Experimental studies of nucleon structure functions are proposed for the Laser Electron Gamma Source (LEGS) facility at Brookhaven National Lab and the large acceptance detector at Thomas Jefferson National Accelerator Facility (TJNAF). The experiments at LEGS focus on the Drell-Hearn-Gerasimov sum rule, a sum rule of fundamental importance, and utilize a polarized photon beam and a polarized target. The experiments at TJNAF utilize the newly completed CLAS detector to measure the four structure functions which describe kaon electropoduction. These in turn will provide tests for models of both the production process and the structure of the nucleon resonances.

提出了在布鲁克海文国家实验室的激光电子伽玛源（LEGS）设施和托马斯·杰斐逊国家加速器设施（TJNAF）的大接收探测器上进行核子结构函数的实验研究。在LEGS的实验集中在Drell-Hearn-Gerasimov求和规则，这是一个重要的求和规则，并利用偏振光子束和偏振目标。在TJNAF的实验中，利用新完成的CLAS探测器测量了描述kaon电产生的四种结构函数。这些反过来将为生产过程和核子共振结构的模型提供测试。
