| 摘 要： | 以γN→πN′反应为例说明了极化实验的类型、自旋观测量同独立幅度的关系、实验上如何得到自旋观测量及实现完全测量等.也介绍了极化固体靶的原理和结构、靶材料的选取原则和适合遍举测量的4π型谱仪及其国际状况等.光致反应中的极化实验和遍举测量将是使用SLEGS从事核物理实验的重要手段. The relationship between polarization observables and indepedent amplitudes, measurements of polarization observables and complete measurement for γN→πN′ are illustrated. The principle and structure of polarization nucleon solid targets, the principle of choosing target material and 4π detectors suitable for exclusive measurements are discussed. The polarization experiments and exclusive measurements are very singnificant for SLEGS.

| Abstract: | The relationship between polarization observables and indepedent amplitudes, measurements of polarization observables and complete measurement for γN→πN′ are illustrated. The principle and structure of polarization nucleon solid targets, the principle of choosing target material and 4π detectors suitable for exclusive measurements are discussed. The polarization experiments and exclusive measurements are very singnificant for SLEGS. |
