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.
