Query: A $J^\pi = 0^-$ Resonance for $\pi NN \to \pi NN $ in the Skyrme Model   The scattering of pions on a dibaryon configuration is analyzed within the
$SU(2)$ Skyrme model. It is shown that this model leads to a low-lying
$(J^P,I)= (0^-,2)$ resonance. The possibility that this resonance corresponds
to one proposed recently in the context of double charge exchange pion
scattering on nuclei is discussed. Given the setup used in those experiments we
also show that a resonance with isospin assignment $I=0$ cannot be excited
according to the description presented here.
