摘要：

The first absolute experimental determinations of the differential cross sections for the formation of ground-state positronium are presented for He, Ar, H-2, and CO2 near 0 degrees. Results are compared with available theories. The ratio of the differential and integrated cross sections for the targets exposes the higher propensity for forward emission of positronium formed from He and H-2.
