Measurements of positron-methane differential scattering cross sections
- 1. Department of Physics and Astronomy, Wayne State University, Detroit, Michigan 48202 (United States)
Description
Relative differential cross sections (DCS close-quote s) have been measured for 4 to 200 eV e+-CH4 quasielastic scattering (elastic scattering plus rotational and vibrational excitations) from 30 degree to 135 degree in a crossed-beam experiment. The observed DCS behavior, including diffraction effects at low energies, is very similar to that found earlier for e+-Ar elastic scattering. Comparisons between (e+,e-)-(CH4,Ar) DCS measurements suggest that observed diffraction effects may be correlated with the sign of the net interaction potential and the degree of spherical symmetry of the target. copyright 1997 The American Physical Society
