论文摘要
分析抗原子氢和氦原子。水平偏移和宽度以$ \ bar {p} $ - 核子子阈值散射长度和体积表示。将实验数据与从2009年版的巴黎$ n \ bar {n} $相互作用潜力获得的结果进行了比较。还与1999年版本进行了比较。讨论了$ n \ bar {n} $ quasi结合状态的影响。计算原子2P高精细结构的抗膜片氘，并指出了新测量的重要性。
Anti-protonic hydrogen and helium atoms are analyzed. Level shifts and width are expressed in terms of $\bar{p}$-nucleon sub-threshold scattering lengths and volumes. Experimental data are compared to results obtained from the 2009 version of the Paris $N\bar{N}$ interaction potential. Comparison with 1999 version is also made. Effects of $N\bar{N}$ quasi-bound states are discussed. Atomic 2P hyperfine structure is calculated for antiprotonic deuterium and the significance of new measurements is indicated.
