Single and Double Charge Exchange Excitations of Spin-Isospin Mode

Single and Double Charge Exchange Excitations of Spin-Isospin Mode

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 wi...
