A cross section enhancement, persisting to high momentum transfer, has been observed around 1HBAR omega in excitation energy in spectra from inelastic proton-, alpha- and electron scattering on Zr-90, Sn-116, Pt-196 and Pb-208. Data are presented for (p,p') at 201 MeV, (alpha,alpha') at 120 MeV and analyzed together with existing data obtained with 133.8 MeV polarized ((p) over right arrow,p') on Sn-116 and electron-scattering data on Sn-116 and Pt-196. Two different interpretations of the observed enhancement are discussed: that of the incoherent sum of all 1HBAR omega cross section and alternatively the sum over the isoscalar normal modes of all multipolarities.</p
