In this paper we present a new result involving the properties of the Clebsch–Gordan coefficients well-used in atomic physics. We also demonstrate a practical use of this result: a new and simple method of calculation of unit tensor operators of multi-electron atoms while working within the Slater–Condon scheme. This results in a significant increase in the ease of implementation of multi-electron...
In a previous paper a method of calculating atomic physics data, energy levels and photo- and collisional-excitation rates using a restricted set of Slater determinants was demonstrated. This paper extends that work to demonstrate the method of calculating a generalisation of coefficients of fractional parentage using a restricted, and already known, set of Slater determinants. These coefficients...
