PsH的第二束缚态
Second bound state of PsH
摘要：
PsH的第二束缚态的存在，这是电子稳定的，也是稳定的对正电子湮没正常的2伽玛和3伽玛过程证明了明确的计算。这种状态可以在2，4So对称性中找到，其中两个电子处于自旋三重态。解离进入H（2 p）+ Ps（2 p）通道的结合能为6.06 × 10 ~（-4）Hartree。状态的主要衰变模式将是辐射衰变成自电离或经历正电子湮灭的配置。具有相同对称性的NaPs系统也是电子稳定的，相对于Na（3 p）+ Ps（2 p）通道的结合能为1.553 × 10 -3 Hartree。
英文摘要：
The existence of a second bound state of PsH that is electronically stable and also stable against positron annihilation by the normal 2gamma and 3gamma processes is demonstrated by explicit calculation. The state can be found in the 2,4So symmetries with the two electrons in a spin triplet state. The binding energy against dissociation into the H(2p) + Ps(2p) channel was 6.06x10-4 Hartree. The dominant decay mode of the states will be radiative decay into a configuration that autoionizes or undergoes positron annihilation. The NaPs system of the same symmetry is also electronically stable with a binding energy of 1.553x10-3 Hartree with respect to the Na(3p) + Ps(2p) channel.
