论文摘要
我们已经研究了一电子和单人离子的2s状态的辐射衰变，其中两光子机制起着重要作用。由于核尺寸校正，电子和muon离子中2s状态的辐射衰减在质量上有所不同。基于准确的相对论计算，我们引入了两参数近似，这使得描述了具有高精度的偏振发射光子的两光角差异过渡概率。分别研究了用线性和圆极化的光子发射。我们还研究了极化初始和最终状态的过渡概率。对原子数为1 <z <120的离子进行了研究。
We have studied the radiative decay of the 2s state of one-electron and one-muon ions, where the two-photon mechanism plays an important role. Due to the nuclear size corrections the radiative decay of the 2s state in the electron and muon ions is qualitatively different. Based on the accurate relativistic calculation, we introduced a two-parameter approximation, which makes it possible to describe the two-photon angular-differential transition probability for the polarized emitted photons with high accuracy. The emission of photons with linear and circular polarizations was studied separately. We also investigated the transition probabilities for the polarized initial and final states. The investigation was performed for ions with atomic numbers 1 < Z < 120.
