We study the sum rules of double Gamow-Teller (DGT) excitations through double spin-isospin operator (σt­)2 In general, 2+states in the granddaughter nuclei have dominant transition strength in DGT excitations and 0+states are weak, except in T = 1 mother nuclei in which 0+strength is competitive with 2+strength. A possibility to extract the unit cross section for the DGT transition strength is pointed out in the (#x03C3;t­)2 excitation of double isobaric analog state (DIAS) in T = 1 nuclei.
