Abstract:The ratios of the widths ofK levels of heavy elements with atomic number 70 to 92 have been calculated with relativistic wave functions, retardation, screening and field theoretical corrections to relativistic energy. The calculated values have been compared with the available observed data and good agreement has been obtained.
Keywords:Width of lines            K lines of heavy elements  field theoretical corrections  retardation effect  transition probabilities  radiative width
