We carried out calculations on the basis of the Zdanovskii-Mikulin rule. The radii of the ions of the actinides americium and curium(III) (0.099 nm) are closest to the radius of the neodymium ion (0.0995 nm), and the radius of the californium ion (0.0976 nm) is closest to the radius of the promethium ion (0.0979 nm). It may accordingly be assumed that the activity coefficients of americium and curium are approximately equal to the activity coefficients of neodymium and that the values for californium are approximately equal to the values for promethium.
