Quasielastic scattering cross sections have been measured with a 950 MeV/c π- beam on targets of 2H, 6Li, C, Ca, Zr, and 208Pb, over a range of three-momentum transfers from 350 through 650 MeV/c. Results for carbon are compared to a finite-nucleus continuum random-phase approximation calculation including distortions. The pion spectra at our lowest range of momentum transfers show less scalar/isoscalar correlation than predicted.
