We develop a well-posed multiparticle Coulomb scattering problem based on asymptotic solutions of a Coulomb multichannel scattering problem constructed in the adiabatic representation. A key feature of the studied problem is that the nonadiabatic channel coupling matrix is nontrivial at large internuclear distances. We consider the scattering problem in the case with an arbitrary momentum value and study solutions for small channel coupling matrix values in detail, constructing explicit representations for the asymptotic solution of the scattering problem.

具有非绝热通道耦合的库仑多通道散射问题的渐近解

我们基于在绝热表示中构建的库仑多通道散射问题的渐近解开发了一个适定的多粒子库仑散射问题。所研究问题的一个关键特征是非绝热通道耦合矩阵在大核间距离处是重要的。我们在具有任意动量值的情况下考虑散射问题，并详细研究小通道耦合矩阵值的解决方案，为散射问题的渐近解决方案构建显式表示。
