Predicted halflives of transuranium nuclei

We are currently writing a monograph tentatively entitled The Elements Beyond Uranium for Wiley-Interscience. Chapters on the discovery of the transuranium elements, their chemical and physical properties, their nuclear properties, experimental techniques of studying them, their presence in nature, superheavy elements nuclear synthetic techniques, and practical applications have been written or are planned. The expected length of the book is approx. 250 pages. In connection with this effort, we have reviewed existing data on the halflives for electron capture, α and β-decay and spontaneous fission for the transuranium nuclei and we have used a set of semiempirical systematics to predict the halflives of unknown transuranium nuclei for Z = 93-110, and neutron numbers between the neutron and proton drip lines. A portion of these predictions (for the lighter actinides) is shown
