摘要: A single channel Titchmarsh-Weyl resonance scattering theory is extended to a coupled equations formulation. It demonstrated that the intrinsic simplicity of persists also in multichannel case. Explicit theorems connection with case are proved, and simple Wronskian expressions for resonant wave functions related physical quantities derived. The computational features illustrated by an application non-trivial curve crossing problem. numerical results display detailed behaviour poles complex plane. relevant diabatic and/or adiabatic limits as well effect strength interaction on structures studied. Applications modeling laser photofragment spectroscopy data finally mentioned
