p̄3He湮灭截面是在动量区间（50÷60）MeV/c中首次测量的。 LEAR-CERN 的 Streamer Chamber Collaboration (PS179) 收集的约 9000 张图片已被扫描。发现六个事件，对应σann=1850±700 mb。将结果与当前在低 p̄ 动量区域中可用的测量集进行比较。
The p̄3He annihilation cross section is measured for the first time in the momentum interval (50÷60) MeV/c. About 9000 pictures collected by the Streamer Chamber Collaboration (PS179) at LEAR–CERN have been scanned. Six events are found, corresponding to σann=1850±700 mb. The result is compared to the set of measurements presently available in the region of low p̄ momentum.
