✦ Synopsis

We study sum rules for charge exchange operators of the Gamow-Teller and Fermi type and explore what can be learned from them about proton-neutron pairing in T = 0 and T = 1 channels. We consider both energy weighted (EWSR) and non-energy weighted (NEWSR) sum rules. We use a schematic Hamiltonian to stress the distinctive roles of T = 1 and T = 0 pair interactions and correlations in the sum rules. Numerical results for 44 Ti are presented for both schematic and realistic interactions.
