A broad peak was systematically observed at about 10 MeV above the Gamow-Teller resonance in the 90Zr, 120Sn, 140Ce, 208Pb (p,n) reactions at Ep = 41 MeV. The angular distribution shapes of these peaks support the interpretation that they they correspond to ΔL = 1 state. The data are compared with TDA-DWBA calculations.
