摘要:

本文用真实强子动力学方法,考虑库仑力,描述了低能质子-氘辐射俘获和~ 3 He的二体和三体光致衰变。研究了单核子电磁流算符相对论修正对观测量的敏感性。相对论自旋轨道电荷的显着影响被发现的矢量分析功率在质子-氘辐射捕获和束靶平行-反平行自旋不对称的三体光蜕变的3 He。

英文摘要:

Proton-deuteron radiative capture and two- and three-body photodisintegration of 3He at low energy are described using realistic hadronic dynamics and including the Coulomb force. The sensitivity of the observables to the relativistic corrections of one-nucleon electromagnetic current operator is studied. Significant effects of the relativistic spin-orbit charge are found for the vector analyzing powers in the proton-deuteron radiative capture and for the beam-target parallel-antiparallel spin asymmetry in the three-body photodisintegration of 3He.
