9412479 Hicks The first nucleon resonance will be studied in carbon via photoproduction using linearly polarized gamma rays at the Laser Electron Gamma Source at Brookhaven National Lab. Decay of the resonance into a pion and nucleon will be observed. A related measurement will be carried out at the TRIUMF lab in Canada using polarized protons to excite the resonance. The objective is to study the effect of the nuclear medium on the fundamental nucleon resonance. An experiment will be initiated at CEBAF to study electroproduction of hyperons. The objective here is to constrain constituent-quark models of these resonances ***

9412479希克斯第一个核子共振将在布鲁克海文国家实验室的激光电子伽马源上使用线性偏振伽马射线通过光生作用在碳中进行研究。 将观察到共振衰减为π介子和核子。 相关的测量将在加拿大的TRIUMF实验室进行，使用极化质子激发共振。 目的是研究核介质对基本核子共振的影响。 CEBAF将启动一项实验，研究超子的电产生。 这里的目标是约束这些共振的组分夸克模型 ***
