本文介绍了一种适用于三体系统的扭曲波Faddeev方法，它是在Bencze和Reish以及Birse和Reish的基础上，利用多极展开法选择重排通道中的部分相互作用作为第一Faddeev方程中的三体扭曲势.其结果是，第二和第三个Faddeev方程的作用大大降低。截断多极展开，丢弃第二和第三个方程，使我们回到著名的连续介质离散耦合通道(CDCC)方法。讨论了这些方法之间的关系。尽管CDCC方法有困难，但它比完全的Faddeev计算要容易得多。
A distorted waves Faddeev method for three-body systems is introduced, following Bencze and Redish and Birse and Redish, by using a multipole expansion to select parts of the interactions in rearrangement channels to serve as three-body distorting potentials in the first Faddeev equation. The consequence is a greatly reduced role for the second and third Faddeev equations. Truncating the multipole expansion and discarding the second and third equations reduces us back to the well-known continuum discretized coupled channels (CDCC) method. The relations among these methods are discussed. Despite the difficulties of the CDCC method, it is much easier than a full Faddeev calculation.© 1996 The American Physical Society.
