• Intensity ratios of mesonic x-ray lines$$K_{\alpha _1 } , K_{\alpha _2 }$$ and$$L_{\alpha _1 } , L_{\beta _2 }$$

Intensity ratios ofμ-mesonic x-rays in some heavy elements are discussed. Intensity ratios of the$$K_{\alpha _1 } /K_{\alpha _2 }$$ and$$L_{\alpha _1 } /L_{\beta _2 }$$ lines have been calculated for206Pb,209Bi and238U with relativistic wavefunctions and retardation effect. Though for a refined calculation, it is necessary to take into consideration several features that are peculiar to mesonic atoms, the present calculations have shown that the observed intensity ratios of mesonic x-rays are not anomalous.

• On the widths ofK levels of heavy elements

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.
