Polarization Transfer in (d,p) Reaction

测量了E， d=18 MeV下（d,p）反应的偏振传递系数（P_y,K^_,K^ y__ -K^y_，K^y_等）以及（d,p）反应的截面和分析功率（A_y,A_<yy>,A_<xx>-A_<xz>）和相应的（d,d）散射。在观测值中，和（K^ y__k ^y_）对张量相互作用敏感。在（d,d）数据分析中，张量分析能力对于获得t_r -张量项贡献具有重要作用。然而，在（d,p）数据的DWBA分析中，这些张量敏感观测值对氘核d态效应有很强的依赖性。而且这些可观测量也依赖于中心力的相互作用，所以我们通过组合可观测量，引入了两个新的变量，它们只依赖于张量的相互作用。这两个变量都与氘核波函数的d态振幅呈明显的正比关系，并且这些变量的实验值可以由任何可靠的氘核波函数很好地再现。结果表明，在该能量区氘核d态效应几乎具有（d,p）反应中所有部分张量型相互作用。（d,p）反应中最常见的极化转移观测值是K^y_，它与自旋翻转概率直接相关，用于研究自旋-自旋相互作用或氘核d态效应。然而，目前对这一观测结果的分析表明，K^y_对中心势有很强的依赖性，并且比d态效应本身为研究扭曲势或反应机制提供了新的信息。

Polarization transfer coefficients (P_y,K^_,K^y_-K^y_,K^y_ etc) have been measured in several (d,p) reactions at E,_d=18 MeV together with cross sections and analyzing powers (A_y,A_<yy>,A_<xx>-A_<xz>) of the (d,p) reactions and corresponding (d,d) scatterings. Among the observables, and (K^y_-K^y_) are found to be sensitive to the tensor interactions. On the (d,d) data analysis the tensor analyzing powers have an essential role for obtaining a T_r-tensor term contribution. On the DWBA analysis of the (d,p) data however, these tensor sensitive observables show very strong dependences on deuteron D-state effect.And further these observables depend also on the central force interactions, so we have introduced, by combining observables, two new variables which depend on the tensor interaction alone. Both variables show a distinct proportional property to the D-state amplitude of deuteron wave function and tile experimental values of these variables are fairly well reproduced by any reliable deuteron wavefunctions. This result shows that in this energy region the deuteron D-state effect have almost all parts of the tensor type interactions in (d,p) reaction.The most popular polarization transfer observable of (d,p) reaction is K^y_, which is directly connected to the spin flip probability and used for the investigation of the spin-spin interaction or the deuteron D-state effect.Present analysis for this observable, however, shows that the K^y_ as very strong dependence on central potentials and brings about new informations for studying distorting potentials or reaction mechanisms than the D-state effect itself.
