Abstract:
The Weakest Bound Electron Potential Model theory is used to calculate transition probability-values and oscillator strength-values for individual lines of Sc(III) and Y(III).In this method, by solving the Schr?dinger equation of the weakest bound electron, the expressions of energy eigenvalue and the radial function can be obtained. And a coupled equation is used to determine the parameters which are needed in the calculations. The obtained results of Sc(III) from this work agree very well with the accepted values taken from the National Institute of Standards and Technoligy (NIST) data base, most deviations are within the accepted level. For Y(III) there are no accepted values reported by the NIST data base. So we compared our results of Y(III) with other theoretical results, good agreement is also obtained.

摘要:
利用最弱受约束电子势模型理论计算了二价钪离子和二价钇离子的能级间跃迁几率和振子强度的数值. 二价钪离子的计算结果与美国国家标准技术研究院(NIST)所给出的可接受值吻合良好. 二价钇离子的计算结果也与现有的其他理论方法的计算结果十分接近.
