Question

What is Coupling of bound and unboun continuum state

Answer 1

In quantum physics, a unbound state is a special quantum state of a particle subject to a potential such that the particle has a tendency to remain localised in one or more regions of space. We can solve for the allowable energy states of a particle, whether it is bound, or trapped, in a potential well or is unbound, having the energy to escape. Namely, since the loosely bound systems often require the coupling to breakup states, a reaction model with core excitation implies that both bound and unbound states need to have core excited components.
