Note on a Possible Scheme for the Assignment and Prediction of Radioactive Periods

Families of odd nuclei differing from each other only by $\alpha$-units show some evidences of a certain type of regularity in their stability against $\beta$-processes. The assumption that a similar regularity holds for all such families permits the unique assignment to the correct isotope of many known radioactive periods and the prediction of many yet unknown lifetimes.
