The elastic scattering and total cross sections for negative pi mesons on hydrogen were measured at 130 and 152 Mev. At both energies, the number of electrons arising from the charge exchange scattering were determined with a Cherenkov counter. At 152 Mev, recoil protons were counted, and were distinguished from pi mesons by energy loss in a scintillator. The real part of the forward scattering amplitade was determined to be 0.243 plus or minus 0.015 and 0.218 plus or minus 0.016, in units of the meson Compton wavelength, at 130 and 152 Mev, respectively. These values agree within limits of statistical error with the predictions from dispersion relations. (auth)
