$H^{+}_{2}$分子离子$2pσ_{u}(\upsilon = 1)$振动态的相对论修正和QED修正
Relativistic and QED corrections to the $2pσ_{u}(\upsilon = 1)$ vibrational state of the $H^{+}_{2}$ molecular ion
摘要：
对最近发现的第一振动$2pσ_u$态进行了相对论和QED修正。这个态具有极小的非相对论结合能$E_B=1.085045252(1)\times10^{-9}$ a. u。它的波函数在$R\approx100$ a. u处具有最大值。并延伸到数百个。结果表明，这种状态不会消失，如果高阶相对论和QED的修正，包括Casimir--Polder效应，考虑。
英文摘要：
Relativistic and QED corrections to the recently discovered first vibrational $2pσ_u$ state are presented. This state has an extremely small nonrelativistic binding energy $E_B=1.085045252(1)\times10^{-9}$ a.u. Its wave functions has a maximum at $R\approx100$ a.u. and extends up to several hundreds. It is shown that this state does not disappear if higher order relativistic and QED corrections, including the Casimir--Polder effect, are taken into account.
