摘要
Data are reported on (p) over bar p --> pi(0)pi(0) over the range of laboratory momenta 600 to 1940 MeV/c. The shapes of angular distributions are similar to earlier data of Dulude et al. above 1100 MeV/c, but show some systematic disagreements. The absolute normalisation disagrees seriously. An amplitude analysis favours the normalisation reported here. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
