Description

Hydrogen formation has been observed following proton impact on positronium. This is the first observation of charge exchange involving a positronium target. The cross section for hydrogen formation has been experimentally determined at proton energies of 11.3, 13.3, and 15.8keV. Values of σH=26(±9), 7.8(±2.3), and 7.6(±4.4)x10-16cm2 were obtained, in reasonable agreement with recent calculations. copyright 1997 The American Physical Society
