摘要

利用极化氘核束和聚乙烯靶，在原子核内部靶站获得了弹性质子-质子散射的分析功率。利用闪烁计数器的时间和幅度信息来选择有用的事件。氢的不对称性是通过减去碳背景得到的。所得的分析功率值与部分波分析SAID在500和650 MeV/核子束流能量下的预测结果进行了比较。

Analyzing power in Quasi-elastic proton-proton scattering at 500 and 650 MeV/nucleon

Analyzing power in elastic proton-proton scattering was obtained at the Nuclotron Internal Target Station using a polarized deuteron beam and a polyethylene target. The selection of useful events was performed using the time and amplitude information from scintillation counters. The asymmetry on hydrogen was obtained by the subtraction of the carbon background. The obtained analyzing power values are compared with the predictions of the partial-wave analysis SAID at the beam energies of 500 and 650 MeV/nucleon.
