论文摘要
在德国ForschungszentrumJülich的凉爽同步加速器舒适的弹性deuteron-碳散射中，对矢量分析能力进行了测量。已经使用了170至380 MEV之间的七个动力学束能。注入了偏光deuteron源的矢量偏振光束，加速到最终所需的能量，并存储在舒适中。细针状钻石带被用作碳靶，横梁被缓慢地转向。使用各种闪烁体和草管层识别出弹性散射的杜特龙。在文献中存在数据（200和270 MEV）中，可以找到角形的出色一致性。通过将分析能力的绝对尺度拟合到这些参考文献的绝对尺度来推断出的数据的光束极化。我们的结果扩展了世界数据集，对于在存储环上的未来电动偶极矩搜索的极化是必要的。它们也将作为偏振强体 - 二体散射的理论描述的输入。
A measurement of vector analyzing powers in elastic deuteron-carbon scattering has been performed at the Cooler Synchrotron COSY of Forschungszentrum Jülich, Germany. Seven kinetic beam energies between 170 and 380 MeV have been used. A vector-polarized beam from a polarized deuteron source was injected, accelerated to the final desired energy and stored in COSY. A thin needle-shaped diamond strip was used as a carbon target, onto which the beam was slowly steered. Elastically scattered deuterons were identified in the forward direction using various layers of scintillators and straw tubes. Where data exist in the literature (at 200 and 270 MeV), excellent agreement of the angular shape was found. The beam polarization of the presented data was deduced by fitting the absolute scale of the analyzing power to these references. Our results extend the world data set and are necessary for polarimetry of future electric dipole moment searches at storage rings. They will as well serve as an input for theoretical description of polarized hadron-hadron scattering.
