在质子撞击正电子后，已观察到氢的形成。这是第一次观察到涉及正电子靶的电荷交换。在质子能量为11.3、13.3和15.8keV时，实验确定了氢生成的横截面。得到{sigma}{sub H}=26（{plus_minus}9）、7.8（{plus_minus}2.3）和7.6({plus_minus}4.4){times}10{sup -16}cm{sup 2}的值，与最近的计算结果基本一致。{版权所有}{ital 1997} {ital美国物理学会}
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 {sigma}{sub H}=26({plus_minus}9), 7.8({plus_minus}2.3), and 7.6({plus_minus}4.4){times}10{sup -16}cm{sup 2} were obtained, in reasonable agreement with recent calculations. {copyright} {ital 1997} {ital The American Physical Society}
