3He Spin-Dependent Cross Sections and Sum Rules
摘要:
本文测量了四动量转移0.1 < Q^2< 0.9 GeV^2时\vec{^3He}(\vec{e},e ')X}反应在准弹性区和共振区的自旋相关截面.自旋结构函数已被提取,并用于评估核Burkhartt-Cottingham和扩展的GDH求和规则的第一次。脉冲近似和精确的三体Faddeev计算的数据在准弹性区域进行了比较。
英文摘要:
We present a measurement of the spin-dependent cross sections for the \vec{^3He}(\vec{e},e')X} reaction in the quasielastic and resonance regions at four-momentum transfer 0.1 < Q^2< 0.9 GeV^2. The spin-structure functions have been extracted and used to evaluate the nuclear Burkhardt--Cottingham and extended GDH sum rules for the first time. Impulse approximation and exact three-body Faddeev calculations are also compared to the data in the quasielastic region.
