摘要：

A high-statistics (100 000 events) measurement of photoproduction of charged pion pairs on protons is reported in two parts. First, the measured cross sections are presented in a three-dimensional data matrix where all the dynamical features are explicitly shown. Second, fitting the data in the energy region 2.6-6.8 GeV with various assumptions on ρ production indicates that dσdt|t=0 for the photoproduction of ρ decreases with increasing energy similar to πN scattering. © 1969 The American Physical Society.
