AN INVESTIGATION OF THE ISOTOPES OF AMERICIUM AND CURIUM

Description: Isotopes of americium and curium with mass numbers less than 242 have been produced by cyclotron bombardment techniques, and several of their nuclear properties have been investigated. The partial alpha half-lives of Am{sup 239}, Cm{sup 241}, and Cm{sup 240} and the partial half-life for spontaneous fission of Cm{sup 240} were measured. The alpha decay daughter of Cm{sup 238} was found and evidence for the discovery of Am{sup 237} (an {approx}1 hour electron capture activity) and Cm{sup 239} (an {approx}10 hour electron capture activity) has been presented. An Appendix indicating the conditions for separation of the plus three actinides by selective elution from ion exchange resin with citric acid has been included.

Barbituric Acids. V. 5-substituted-mercapto Derivatives of 5-isoamylbarbituric Acid

Description: Since no mention has been found in the literature of any 5-substituted mercapto-5-alkyl derivatives of barbituric acid, it was thought to be of interest to prepare a series of compounds containing sulfur attached directly to the barbituric acid nucleus. 5-substituted mercapto-5-isoamylbarbituric acids were chosen as representative of barbituric acids in which the alkyl group has a fairly high molecular weight.
