The structure of deformed proton emitters is studied in a coupled-channels treatment. The wave function of a decaying state is determined as a standing wave, i.e., for an energy that is real. The decay rate is calculated from a Green’s function method, treating the influence of the long-range Coulomb multipole interactions to first order. The results are compared to predictions made in the adiabatic limit and to measurements. It is shown that the decay of the ground state to the ground state of is quite sensitive to deformation in the spin-orbit force. It is found that the ground state decay of is poorly described in the coupled-channels approach. This is ascribed to Coriolis mixing, which is too strong in the absence of pairing effects.
