For ([pi][sup +],[pi][sup [minus]]) double charge exchange on [sup 27]Al, an excitation function at 5[degree] has been measured over a range of incident pion energies from 100 to 293 MeV for transitions to both the ground state and to a doublet at 1.75 MeV of excitation in the final nucleus [sup 27]P. The shapes of these excitation functions are strikingly different, with the g.s. data exhibiting an interferencelike dip near 150 MeV and the excited state falling smoothly above 150 MeV.
