氘核通过物质时的张量极化

Tensor polarization of deuterons passing through matter

V. G. Baryshevsky, A. R. Bartkevich

摘要:

它示出的张量极化的氘核束,这是由于自旋二向色性效应而产生的幅度,取决于明显的检测器,登记的氘核通过目标传输的角宽度。即使当探测器的角宽度远小于多次库仑散射的均方角时,光束的张量偏振也明显依赖于再散射。当探测器的角宽远大于多次库仑散射的均方角(以及弹性核散射的特征角)时,张量极化仅由氘-核相互作用的总反应截面决定,弹性散射过程对张量极化没有贡献.

英文摘要:

It is shown that the magnitude of tensor polarization of the deuteron beam, which arises owing to the spin dichroism effect, depends appreciably on the angular width of the detector that registers the deuterons transmitted through the target. Even when the angular width of the detector is much smaller than the mean square angle of multiple Coulomb scattering, the beam's tensor polarization depends noticeably on rescattering. When the angular width of the detector is much larger than the mean square angle of multiple Coulomb scattering (as well as than the characteristic angle of elastic nuclear scattering), tensor polarization is determined only by the total reaction cross sections for deuteron-nucleus interaction, and elastic scattering processes make no contribution to tensor polarization.
