Book excerpt: Excitation functions have been determined for the spallation and fission reactions induced in plutonium isotopes by 20 to 50 Mev helium ions. The method employed consisted of cyclotron bombardments of plutonium oxide followed by the chemical isolation and alpha or beta counting of radioactive reaction products. Formation cross sections are given where possible for the curium and americium spallation products corresponding to ([alpha], n), ([alpha],2n), ([alpha],3n), ([alpha],4n), ([alpha]5n), ([alpha], p), ([alpha], pn or d), ([alpha], p2n or t), and ([alpha], p3n) reactions in Pu238, Pu239, and Pu242. Fission yield curves and fission cross sections for Pu238 and Pu239 serve to define the characteristics of the ([alpha], f) reaction for plutonium isotopes. Chemical procedures are outlined for the separation of both spallation and fission product elements in a sequence of operations performed on the entire dissolved target.

This book was released on 1957 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A radiochemical study of fission and spallation products produced by bombardment of U233, U235, and U238 with 18-46 Mev helium ions has been made. As in the case of similar studies using isotopes of plutonium as targets, most of the reaction cross section is taken up by fission. Also, the pronounced increase of the total cross section for ([alpha], xn) reactions with increasing mass number of the target that was observed for plutonium targets is observed for uranium targets.

Available in PDF, EPUB and Kindle. Book excerpt: The results of a radiochemical study of fission and spallation products induced in U234, U235, and U/sup 236 and spallation products induced in U238 by deuterons of less than 24 Mev are presented. The (d, n) reactions are interpreted as the result of direct interactions between the deuteron and the target nuclei, while the (d, n) reactions are thought to be taking place primarily by compound-nucleus mechanisms. A method for predicting the peak values of the cross section for (d, xn) and (alpha, xn) reactions on uranium and plutonium isotopes is given for x = 2, 3, or 4. The peak-to-valley ratios of the fission-yield curves for U/sup 234, U235, U236, and U/ sup 238/ bombarded with deuterons of energies of about 23 Mev were studied, and no significant differences were found. Excitation functions for the (d, gamma) reactions of U234, U236, and U238 rise to a maximum of about a millibarn at a bombarding energy between 15 and 20 Mev. The results of these measurements are seen to be consistent with the excitation functions for (p, gamma) and (alpha, gamma) reactions. The 60minute neptunium activity which had previously been assigned to Np241 was identified as an isomer Np/sup 240/. Accompanying the decay of this Np24° are gamma rays of energies 1160, 1000, 915, 595, 565, 435, 245, 16O, and 85 kev. Np241 has now tentatively been found to have isomers with half lives of 16 minutes and 3.5 tours. A study of the decay properties of the new isotope Np241 and also of Np233 and Np234 are described.

Available in PDF, EPUB and Kindle. Book excerpt: During his distinguished career spanning more than 50 years, Nobel laureate (Chemistry) Glenn T Seaborg published over 500 works. This volume puts together about 100 of his selected papers. The papers are divided into five categories. Category I consists of papers which detail the discovery of 10 transuranium elements and numerous heavy isotopes of special importance. Category II papers describe the discovery of a number of isotopes which became the workhorses of nuclear medicine or found other applications. Papers in Category III describe how the chemical properties of transuranium elements were originally determined, how chemistry is applied in nuclear sciences, and other chemical investigations, including early work done with the great chemist G N Lewis. Papers in Category IV cover radioactive decay chains and nuclear systematics. Lastly, papers in Category V illustrate how the powerful methods of chemistry are used to explain nuclear reactions in low, intermediate and high energy nuclear physics.
