The Gamow--Teller transition strength from ({ital N},{ital Z}) to ({ital N}{minus}2,{ital Z}+2) nuclei is studied using extended space shell-model calculations. The notion of a giant double Gamow--Teller state is introduced. The application of these ideas to double beta-decay and pion double charge exchange is introduced. A good signature in light-medium mass nuclei of the double Gamow--Teller mechanism in pion double charge exchange from the {ital J}=0 ground state of an even--even nucleus is the excitation of both {ital J}=0{sup +} and {ital J}=2{sup +} states in the final nucleus. {copyright} 1989 Academic Press, Inc.
