Radiative lifetime and oscillator strength values were computed by means of a pseudo-relativistic Hartree–Fock model including core-polarization and compared successfully with experimental data given in the literature for respectively numerous low-lying Cr II 3d44p levels, up to 54784 cm−1, and transitions depopulating these levels. Then transition probability and branching fraction data were also deduced in the wavelength range 1825–94400 Å. Furthermore the extracted radial integral values, obtained with the help of the oscillator strength parameterization method, are given for involved transitions in this work, i.e. 3d44s–3d44p, 3d5–3d44p and 3d44p–3d44d. We confirm our observed previous general trends, noting once again a decreasing of transition radial integral values with filling nd shells of the same principal quantum numbers for ndk(n+1)s ndk(n+1)p transitions.

铬的第二光谱(Cr II),第二部分:低寿命3d过渡的辐射寿命和振荡器强度44p级

通过包括磁芯极化的伪相对论性Hartree-Fock模型计算了辐射寿命和振荡器强度值,并成功地与文献中分别针对大量低洼Cr II 3d的实验数据进行了比较44p级,最大至54784 cm -1,并且过渡减少了这些级。然后,还推导了在1825–94400Å波长范围内的跃迁概率和分支分数数据。此外,给出了在振荡器强度参数化方法的帮助下获得的提取的径向积分值,用于该工作中涉及的过渡,即3d44s–3d44p,3d5–3天44p和3d44p–3d44d。我们确认了我们观察到的先前的总体趋势,并注意到随着填充,过渡径向积分值再次减小ñ相同主量子数的d个壳 ñdķñ+1个s ñdķñ+1个p个转换。
