Elastic scattering of 162-MeV pions by nuclei

Journal Article · · Phys. Rev. Lett.; (United States)
; ; ; ; ; ; ; ; ; ; ;
The elastic scattering of 162-MeV ..pi../sup +/ and ..pi../sup -/ /sup 9/Be, Si, /sup 5/8Ni and /sup 2/08Pb have been measured. All angular distributions, except for /sup 9/Be, exhibit strong diffraction patterns. Optical-model calculations with matter distributions deduced from electron scattering qualitatively reproduce the data, but better agreement for all but /sup 9/Be can be obtained with suitable modifications. No substantial differences in neutron- and proton-matter radii are indicated.
