We derive the separated Dirac equations, impose quasibound boundary conditions, and obtain the far-field trapping condition $M\\mu^2-qQ\\omega_R>0$, whose weak-binding, same-sign limit is $M\\mu>qQ$. The complex frequencies are computed in the frequency domain and checked against time-domain evolutions.
