模型中的反扭结-扭结()碰撞表现出共振散射，尽管扭结不支持能量可以转移到的任何束缚态。书名/作者：Reach in the Model，Phys.莱特牧师。091602(2011)PRLTAO0031-900710.1103/PhysRevLett.107.091602]推测，相反，能量转移到全组态的集体束缚模式。在这里，我们提出了进一步有力的证据来支持这一猜想。在此基础上，我们构造了一个集体坐标模型(CCM)，该模型基于这个集体束缚模，使得我们能够以惊人的精度再现散射的全部动力学过程。我们还研究了扭结-反扭结()散射及其CCM描述。在这种情况下，辐射的重要作用被发现。
Antikink-kink () collisions in themodel exhibit resonant scattering although thekinks do not support any bound states to which energy could be transferred. In P. Doreyet al.[Kink-Antikink Collisions in theModel, Phys. Rev. Lett. 107, 091602 (2011)PRLTAO0031-900710.1103/PhysRevLett.107.091602] it was conjectured that, instead, energy is transferred to a collective bound mode of the fullconfiguration. Here we present further strong evidence for this conjecture. Further, we construct a collective coordinate model (CCM) forscattering based on this collective bound mode trapped between thepair which allows us to reproduce the full dynamics ofscattering with striking accuracy. We also study kink-antikink () scattering and its description by a CCM. In this case a significant role of radiation is discovered.
