In the present work, we are discussing the Klein–Gordon equation describing relativistic spinless particles evolving in the (stationary) magnetar’s crust. With the wave function expressed in terms of Mathieu’s functions, we compute first-order transition amplitudes, pointing out the role of the strong magnetic induction in transitions to states which may be characterized by values of the model’s parameters in instability bands.
