  The energy distributions of the Gamow-Teller strength are studied for
even-even Xe isotopes with mass numbers from 124 to 142. A self-consistent
microscopic formalism is used to generate the single particle basis, using a
deformed Skyrme Hartree-Fock mean field with pairing correlations in BCS
approximation. The Gamow-Teller transitions are obtained within a quasiparticle
random phase approximation (QRPA) approach using a residual spin-isospin
interaction in the particle-hole and particle-particle channels. We then
discuss the pairing BCS treatment and the determination of the ph and pp
residual interaction coupling constants. We study the GT+ and GT- strength
distributions for the equilibrium nuclear shapes, which are an essential
information for studies of charge-exchange reactions and double-beta processes
involving these isotopes.
