- Аннотация: The vertex constant for the virtual decay of a nucleus to two charged particles having an arbitrary orbital angular momentum l was explicitly obtained for the first time in the case of a standard expansion of the effective-range function K l(k 2), as well as in the case where the function K 0(k 2) has a pole. The bound state of the 3He nucleus and the resonance states of the 2He and 3He nuclei in the S wave, as well as the resonance states of the 5He and 5Li nuclei in the P wave, are studied as physical examples. For the Np and N d systems, the trajectories of the pole in the complex planes of the momentum and the corresponding renormalized vertex constant are constructed for the transition from a resonance state to a virtual state as the Coulomb interaction is switched off gradually. © 2010 Pleiades Publishing, Ltd.
