Análise revisada e estendida de níveis do Kr VII

Abstract

This work was motivated by improving and expanding existing knowledge related to the study spectral six times ionized Krypton (Kr VII). An revised and extended analysis of Kr VII already published, also we studied new configurations. The purpose of this study is to provide structural information of energy levels and atomic parameters of the Kr VII. Initially we performed the isoelectronic sequence of Zn I, in order to revise configuration the 4p4d, which has 12 energy levels. We also studied the isoelectronic sequence of the configurations 4s6p, 4p5s and 4s5f for the odd parity; 4s6d for the even parity. The theoretical predictions on the structure of the configurations used in the analysis were obtained from the computer code developed by Robert Cowan, which provides atomic parameters by means approximation of Hartree-Fock with relativistic corrections. This study was conducted in collaboration with researchers of Centro de Investigaciones Opticas - CIOp (La Plata, Argentina), whose data used in this work were obtained by two spectral light sources: a theta-pinch and a capillary discharge. Of the results obtained, we determined all energy levels of the configurations 4p5s and 4p4d, where 78 new transitions were identified for Kr VII.
