摘要

摘要利用能量为 500 兆电子伏/核子的偏振氘核束和聚乙烯靶，在核反应堆内部靶站获得了准弹性质子-质子（pp）散射的分析功率值。利用闪烁计数器提供的时间和振幅信息对有用事件进行了筛选。通过从聚乙烯上积累的数据中减去碳背景，获得了质子的不对称性。分析功率值与 SAID 部分波分析预测值和其他实验数据进行了比较。

Vector Analyzing Power in Quasi-Elastic Proton-Proton Scattering at an Energy of 500 MeV/nucleon

Abstract

The values of the analyzing power in quasi-elastic proton-proton (pp) scattering are obtained at the Nuclotron Internal Target Station using a polarized deuteron beam at an energy of 500 MeV/nucleon and the polyethylene target. The selection of useful events has been performed using the time and amplitude information from scintillation counters. Asymmetry by protons has been obtained by the subtraction of the carbon background from the data accumulated on polyethylene. The analyzing power values are compared with predictions of SAID partial-wave analysis and the data of other experiments.
