Semiempirical branching fractions of the 3 s 2 3 p 2 – 3 s 3 p 3 J = 2 transition array in P II 1

چکیده
A semiempirical method is used to characterize the 3s3p– 3s3p J=2 transition array in P II. In this method Slater, spin-orbit, and radial parameters are fitted to experimental energy levels to obtain a description of the array in terms of LS-coupling basis vectors. The intermediate coupling (IC) and configuration interaction (CI) amplitudes so obtained are then used to predict the branching fractions of transitions within the array. These two configurations are particularly interesting because the 3s3p has been shown to be virtually free of CI but affected by IC, whereas the 3s3p is virtually free of IC but affected by CI. PACS nos.: 32.70.Cs; 32.30.Jc; 34.50.Fa Résumé : Nous utilisons une méthode semi-empirique pour caractériser la série de transitions 3s3p– 3s3p J=2 dans P II. Dans cetta méthode, les paramètres de Slater, de spin–orbite et radial, sont ajustés aux données expérimentales en termes d’une base de vecteurs de couplage LS. Nous obtenons les amplitudes de couplage intermédiare (IC) et d’interaction de configuration (IC) et nous les utilisons pour prédire les rapports de branchement des transitions dans le série. Ces deux configurations sont particulierément intéressantes parce qu’on a découvert que le 3s3p est pratiquement libre de CI, mais est affecte par IC alors que c’est l’inverse pour le 3s3p.

متن کاملLETTER TO THE EDITOR Intermediate coupling branching fractions for UV transitions in ions of the Si and Ge sequences
The use of lifetime measurements for the specification of transition probabilities along isoelectronic sequences is hindered by the fact that virtually no branching fraction measurements exist for multiply charged ions. Part of the reason for this lies in the lack of calibration standards for intensity as a function of wavelength in the ultraviolet region. It has been shown that transitions of ...
متن کاملScale-free random branching trees in supercritical phase
We study the size and the lifetime distributions of scale-free random branching trees in which k branches are generated from a node at each time step with probability qk ∼ k−γ . In particular, we focus on finite-size trees in a supercritical phase, where the mean branching number C = ∑k kqk is larger than 1. The tree-size distribution p(s) exhibits a crossover behaviour when 2 < γ < 3. A charac...
متن کاملPhotodissociation channels for N2O near 130 nm studied by product imaging.
The photodissociation of N(2)O at wavelengths near 130 nm has been investigated by velocity-mapped product imaging. In all, five dissociation channels have been detected, leading to the following products: O((1)S)+N(2)(X (1)Sigma), N((2)D)+NO(X (2)Pi), N((2)P)+NO(X (2)Pi), O((3)P) + N(2)(A (3)Sigma(+) (u)), and O((3)P) + N(2)(B (3)Pi(g)). The most significant channel is to the products O((1)S) ...
