Title: Measurement of x rays from antiprotonic atoms and the effects of the strong interaction. [Level widths and shifts, optical model potential, s-wave scattering length]

Abstract

Antiprotonic atoms were formed with /sup 6/Li, /sup 7/Li, C, Si, P, Fe, Y, Zr, Cs and Yb. Level shifts and widths due to the strong interaction were measured. The results were analyzed using an optical model potential proportional to the nuclear matter density and to an effective anti p-nucleon s-wave scattering length. A phenomenological fit to the data yielded ((0.85 +- 0.38) + i(2.66 +- 0.28)) fm for the effective scattering length. The largest uncertainty in the analysis was the determination of the nuclear matter density at the nuclear surface. In addition, the mass of the antiproton was measured to be 938.236 +- 0.048 MeV.
