| Popis: | Agradecimentos: We are very grateful to Fausto Bredice, who helped us in the preliminary discussions. This research was supported by the Consejo Nacional de Investigaciones Científicas y Tecnicas (CONICET), Argentina, and by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Brazil, Finance Code 001. The support from the Comision de Investigaciones Científicas de la Província de Buenos Aires (CIC), where M.R. and J.R.A. are researchers, is gratefully acknowledged Abstract: A capillary pulsed-discharge and a theta-pinch were used to record Kr spectra in the region of 330-4800 angstrom. A set of 168 transitions of these spectra were classified for the first time. We extended the analysis to twenty-five new energy levels belonging to 3s(2)3p(2)4d, 3s(2)3p(2)5d even configurations. We calculated weighted transition probabilities (gA) for all of the experimentally observed lines and lifetimes for new energy levels using a relativistic Hartree-Fock method, including core-polarization effects COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPES Aberto |
