80‘S和90’S在欧洲核子研究中心对低能反核湮没截面进行了系统的测量，但关于中、重和重核靶的反质子数据很少。ASACUSA在欧洲核子研究中心的合作测量了5.3 MeV下碳的反质子湮没截面：值为(1.73+/-0.25)谷仓。将计算结果与反中子实验数据和理论预测进行了比较。(C)2018爱思唯尔B.V.保留所有权利。
Systematic measurements of the annihilation cross sections of low energy antinucleons were performed at CERN in the 80's and 90's. However the antiproton data on medium-heavy and heavy nuclear targets are scarce. The ASACUSA Collaboration at CERN has measured the antiproton annihilation cross section on carbon at 5.3 MeV: the value is (1.73 +/- 0.25) barn. The result is compared with the antineutron experimental data and with the theoretical previsions. (C) 2018 Elsevier B.V. All rights reserved.
