An excitation function at 5{degrees} has been measured for ({pi}{sup +}, {pi}{sup -}) double charge exchange on the target nucleus {sup 27}Al to both the final ground state and a state at 1.75 MeV of excitation in the final nucleus {sup 27}P. These data were obtained over a range of incident pion energies from 100 to 293.4 MeV using the EPICS facility at LAMPF. The shapes of these excitation functions are strikingly different; the excited state showing similar behavior to non-analog, J{sup {pi}}{sub i}=0{sup +} to J{sup {pi}}{sub f}=0{sup +} transitions and the g.s. data exhibiting an interference-like dip near 150 MeV. This minimum likely involves spin flip because the g.s., {Delta}J{ne}0 transition can involve single spin flip.
