Despite the in-plane orientation of the static ordered moment we find the in-plane polarized magnons to exhibit a larger gap than the out-of-plane polarized ones indicating very strong single-ion anisotropy within the layers. It costs more energy to rotate a spin within the orthorhombic {\\it a-b} plane than rotating it perpendicular to the FeAs layers.","authors_text":"B. B\\\"uchner, M. Braden, N. Qureshi, P.
