Particle-hole stretched states excited in the /sup 26/Mg(p,n)/sup 26/Al reaction at 134 MeV

Strong excitation of both (πd/sub 5/2/,νd/sub 5/2//sup -1/) 5+, 0 (h/2π)ω and (πf/sub 7/2/,νd/sub 5/2//sup -1/) 6-, 1 (h/2π)ω stretched-state strength is observed in the /sup 26/Mg(p,n)/sup 26/Al reaction at 134.4 MeV. The T = 0, 5+ strength is observed to be predominantly in the ground state which has 56% of the strength predicted by a distorted-wave impulse approximation calculation that assumes the extreme single-particle-hole model. Another 17% of this strength is observed in a 5+ state at 3.4 MeV. The 6- strength is split into three isospin components: 61% of the extreme single-particle-hole model T = 0, 6- strength is observed in three states between 6.9 and 11.0 MeV; 58% of the predicted T = 1 strength is observed in nine states between 9.3 and 16.5 MeV; 27% of the predicted T = 2 strength is observed in a single state at 18.2 MeV. The observed 6--state excitation energies are in general agreement with the T = 0 and 1, 6- states observed in the /sup 25/Mg(α,t)/sup 26/Al reaction and with the analog T = 1 and 2, 6- states in /sup 26/Mg observed in inelastic electron and proton scattering. The total observed 5+ strength and its distribution are in good agreement with distorted-wave impulse approximation calculations that use full S-D shell-model wave functions
