The double isovector giant-dipolar state has been observed in the ({pi}{sup {minus}},{pi}{sup +}) {Delta}{ital T}{sub {ital z}}=+2 and ({pi}{sup +},{pi}{sup {minus}}) {Delta}{ital T}{sub {ital z}}={minus}2 double-charge-exchange reactions on {sup 40}Ca and {sup 27}Al. The resonances observed in the ({pi}{sup {minus}},{pi}{sup +}) reaction are closely related via Coulomb energy and isospin symmetry to the resonances measured in the inverse ({pi}{sup +},{pi}{sup {minus}}) reaction on the same nuclei. The new observations provide strong support for the identification of the double giant-dipole state in nuclei. The differences between the self-conjugate and non-self-conjugate cases are outlined.
