| spelling | oai:scholar.sun.ac.za:10019.1/2130 The production of 139Pr and 139Ce in proton-induced reactions Vermeulen, Christiaan Steyn, G. F. University of Stellenbosch. Faculty of Science. Dept. of Chemistry and Polymer Science. Radioisotopes Isotope separation Dissertations -- Chemistry Theses -- Chemistry Thesis (MSc (Chemistry and Polymer Science))--University of Stellenbosch, 2007. Excitation functions and production rates are presented for various Ce and Pr radionuclides formed in the bombardment of 141Pr, natLa and natCe with protons. Extensive measure- ments were performed for 141Pr + p up to 100 MeV and for natLa + p up to 20 MeV. The possibility is investigated to utilize tandem targetry for the production of no-carrier-added 139Ce of high radionuclidic purity, having a Pr target in the higher energy slot followed by a La target in a lower energy slot. 141Pr(p,3n)139mNd!139Pr is investigated as an al- ternative to the direct production route 140Ce(p,2n)139Pr for producing no-carrier-added 139Pr of high radionuclidic purity. The advantages and disadvantages of both production routes are discussed. The simultaneous production of 139Pr and 140Nd using Pr as target is also investigated. Experimental thick-target production rates are presented for Pr ra- dionuclides formed in the bombardment of natCe with protons at incident energies of 20, 26 and 32 MeV. All the experimental excitation functions obtained in this work are compared with theoretical predictions by means of the geometry-dependent hybrid (GDH) model as implemented in the code ALICE-IPPE. The results of this work are also compared with previous literature experimental data, if available. 2008-04-14T13:41:41Z 2010-06-01T08:41:03Z 2008-04-14T13:41:41Z 2010-06-01T08:41:03Z 2007-12 Thesis http://hdl.handle.net/10019.1/2130 en_ZA University of Stellenbosch 4544872 bytes application/pdf application/pdf Stellenbosch : University of Stellenbosch |
