| 摘 要： | 分析了在重离子冷却储存环上测量的辐射电子俘获产生的X射线能谱,得出了K REC光子的相对微分角分布,通过与非相对论理论和全相对论理论的计算结果进行比较,从实验上证明了相对论重离子 原子碰撞中自旋翻转跃迁的存在,实验结果与全相对论理论计算结果一致.同时还证实,重离子体系本身的相对论性质对碰撞过程有重要影响. Radiative electron capture process occurring in high-Z ion-atom collisions studied on the heavy ion storage ring (ERS) is reviewed. The REC differential angular distributions are deduced from the X-ray spectra recorded at various observation angles for 310 and 88 MeV/u U 92+on N 2collisions, respectively. The experimental results are compared with non-relativistic and complete relativistic calculations. Deviations from sin 2θ lab are found in both cases. The contributions to near 0°observation...

| Abstract: | Radiative electron capture process occurring in high-Z ion-atom collisions studied on the heavy ion storage ring (ERS) is reviewed. The REC differential angular distributions are deduced from the X-ray spectra recorded at various observation angles for 310 and 88 MeV/u U 92+on N 2collisions, respectively. The experimental results are compared with non-relativistic and complete relativistic calculations. Deviations from sin 2θ lab are found in both cases. The contributions to near 0°observation... |
