Influence Of Fringing Fields On The Field-Induced Quantum Beats Of Atomic Hydrogen, Gordon W. F. Drake
Influence Of Fringing Fields On The Field-Induced Quantum Beats Of Atomic Hydrogen, Gordon W. F. Drake
Physics Publications
Calculations are presented which include exactly the effects of fringing fields on the electric-field-induced quantum beats of atomic hydrogen. The results explain some recently observed phaseshifts of the quantum beats relative to the predictions of the 'sudden approximation'. The general features produced by finite rise-time and overshoot are discussed.
Vector-Coupling Approach To Orbital And Spin-Dependent Tableau Matrix Elements In The Theory Of Complex Spectra, Gordon W. F. Drake, M. Schlesinger

The power of the Young tableau scheme for labeling a complete spin-adapted basis set in the theory of complex spectra lies in one's ability to evaluate matrix elements of irreducible tensor operators directly in terms of the tableau labels and shapes. We show that the matrix-element rules stated by Harter for one-body operators can be easily derived from simple vector-coupling considerations. The graphical method of angular momentum analysis is used to derive closed-form expressions for the matrix elements of two-body operators. This study yields several interesting new relationships between spin-dependent operators and purely orbital operators. © 1977 The American Physical …

The spin-orbit parameters for the sextet states of the f5 configuration are computed using the Young-tableau techniques developed by Harter. The conceptual and computational advantages over traditional methods are discussed. © 1977 The American Physical Society.
