Theoretical Calculations of Transition Probabilities and Oscillator Strengths for Sc(III) and Y(III)

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.
