  We present results on the production of bound states of $\Theta^+$ in nuclei
using the $(K^+,\pi^+)$ reaction. By taking into account the states obtained
within a wide range of strength of the $\Theta^+$ nucleus optical potential,
plus the possibility to replace different nucleons of the nucleus, we obtain an
excitation spectra with clearly differentiated peaks. The magnitude of the
calculated cross sections is well within reachable range.
