Abstract: The reaction pp -> pp pi(0) was studied with the WASA detector at the CELSIUS storage ring. The center of mass angular distribution of the pi(0) was obtained by detection of the gamma decay products together with the two outgoing protons and found to be anisotropic with a negative second derivative slope, in agreement with the theoretical predictions from a microscopic calculation.
