论文摘要
提出了一种新的分散（渐近）理论，该理论是针对三体（$ a $，$ a $ a $ a $ and $ $）模型的外围次和上级式粒子传输$ a（x，y）b $反应的，其中$ x = y +a +a $ +a $ a +a $ and $ b = a +a +a $，$ a $是转移粒子。它基于分散理论和常规DWBA方法的组合。显式表格是针对确切的三体极振幅和差异横截面的，其中三体（$ a $，$ a $ a $ and $ a $ and $ $）的贡献是转移机制在外围部分幅度中的转移机制的库仑动力学，与$ l_i >> 1 $相对应的部分波，相对于部分波动。对于特定的外围质子和Triton转移反应，对$ L_I >> 1 $的外围部分部分振幅的比较分析对应于一步极和精确的三体极振幅以及“邮政” - Appro-approximation和传统DWBA的后形式的三体极振幅，并与每个人一起执行。它显示了“邮政” - 附属性的绝对不适用性，通常用于获取有关天体物理兴趣的特定渐近归一化系数的信息。
A new dispersion (asymptotic) theory is proposed for the peripheral sub- and above-barrier charged particle transfer $A(x,y)B$ reaction in the three-body ($A$, $a$ and $y$) model where $ x= y +a$ and $B=A+a$, and $ a$ is a transferred particle. It is based on the combination of the dispersion theory and the conventional DWBA method. The explicit forms have been derived for the exact three-body pole amplitude and differential cross section in which the contribution of the three-body ($A$, $a$ and $y$) Coulomb dynamics of the transfer mechanism in the peripheral partial amplitudes, corresponding to partial waves with $l_i>>1$, is taken into account correctly. For the specific peripheral proton and triton transfer reactions, the comparative analysis of the peripheral partial amplitudes at $l_i>>1$ , which correspond to the one-step pole and exact three-body pole amplitudes as well as those of the "post"-approximation and the post form of the conventional DWBA, is performed with each other. It shows the absolute inapplicability of the "post"-approximation usually applied for getting an information about specific asymptotic normalization coefficients being astrophysical interest.
