质子-氘核弹性散射的分析能力

The analysing powers in proton-deuteron elastic scattering

Yu. Uzikov, C. Wilkin

摘要:

结果表明,在小角度质子-氘核弹性散射中,氘核和质子的分析能力之比对理论描述中的细微效应很敏感。这些修正包括基本核子-核子振幅中的横自旋-自旋项和双散射修正。另一方面,对自旋轨道振幅以及与使用氘核作为靶或射弹相关的结合或其他运动学效应的敏感性要小得多。可用的数据与改进的Glauber理论模型的结果一致。

英文摘要:

It is shown that the ratio of the deuteron and proton analysing powers in proton-deuteron elastic scattering at small angles is sensitive to subtle effects in a theoretical description. These include the transverse spin-spin term in the elementary nucleon-nucleon amplitudes and double-scattering corrections. On the other hand there is far less sensitivity to the spin-orbit amplitude and to binding or other kinematic effects associated with the use of the deuteron, as either target or projectile. The available data are in agreement with the results of a refined Glauber theory model.
