This book was released on 2008 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excitation functions for the 1n and 2n exit channels of the 208Pb(51V,xn)259-xDb reaction were measured. A maximum cross section of the 1n exit channel of 2070$+1100\atop{-760}$ pb was measured at an excitation energy of 16.0 ± 1.8 MeV. For the 2n exit channel, a maximum cross section of 1660$+450\atop{-370}$ pb was measured at 22.0 ± 1.8 MeV excitation energy. The 1n excitation function for the 209Bi(50Ti,n)258Db reaction was remeasured, resulting in a cross section of 5480$+1730\atop{-1370}$ pb at an excitation energy of 16.0 ± 1.6 MeV. Differences in cross section maxima are discussed in terms of the fusion probability below the barrier. The extraction of niobium (Nb) and tantalum (Ta) from hydrochloric acid and mixed hydrochloric acid/lithium chloride media by bis(2-ethylhexyl) hydrogen phosphate (HDEHP) and bis(2-ethylhexyl) hydrogen phosphite (BEHP) was studied. The goal of the experiments was to find a system that demonstrates selectivity among the members of group five of the Periodic Table and is also suitable for the study of dubnium (Db, Z = 105). Experiments with niobium and tantalum were performed with carrier (10-6 M), carrier free (10-10 M) and trace (10-16 M) concentrations of metal using hydrochloric acid solution with concentrations ranging from 1 - 11 M. The extraction of niobium and tantalum from mixed hydrochloric acid/lithium chloride media by HDEHP and BEHP as a function of hydrogen ion (H+) concentration was also investigated. The data obtained are used as the basis to discuss the speciation of niobium and tantalum under the conditions studied and to evaluate possible extraction mechanisms. The 74Se(18O,p3n)88gNb excitation function was measured to determine the best energy for producing the 88Nb used in chemistry experiments. A maximum cross section of 495 +- 5 mb was observed at an 18O energy of 74.0 MeV. The half life of 88gNb was measured and determined to be 14.56 ± 0.11 min.

Available in PDF, EPUB and Kindle. Book excerpt: Deep-inelastic reactions between 6.2 MeV/A Xe-136 ions and a thick W-186 target have been used to investigate excited states in neutron-rich tantalum isotopes, establishing new structures in Ta-182 and Ta-183. Spins and parities were determined from angular correlations, internal conversion coefficients deduced from intensity balances, and consideration of transition strengths. The structure and configuration assignments have been established from the measured magnetic properties and alignments of the observed rotational bands, as well as comparison with multi- quasiparticle calculations. Multi-quasi particle calculations using adjusted Nilsson energies and Lipkin-Nogami pairing model were performed for the series of tantalum nuclei between A=181 and A=185.The previously known 1300 ns isomer in Ta-183 was fully characterised with its energy deduced as 1332 keV and a K = 19/2+ assignment. Several new multi-quasiparticle states, including two isomers with 41(5) ns mean-life, K = 29/2- and 70(4) ns (mean-life), K = 41/2-, have been further identified and found to be feeding the known 1300 ns isomer. From the multi-quasiparticle calculations, a three-quasiparticle configuration was assigned to both the K = 19/2+ and 29/2- isomers, while the upper-most isomer at 41/2- was established to have a five-quasiparticle nature.The out-of-beam gamma-ray coincidence data revealed a new level structure in coincidence with tantalum X-rays. Measurements of the magnetic properties of this structure from branching ratios, together with the yields from various data sets using W-186, Re-185, Re-187 and Os-192 targets, enabled an isotopic assignment of this structure to Ta-182. Three isomeric states were found to be feeding the known 10-> isomer in Ta-182. A rotational band built on the 10- isomer has been > observed and was found to be fed by a new 14+, 356 ns (mean-life) > isomer at 1950 keV. Several intrinsic states above this isomer are > also identified. Firm spins and parities have been established up to > the 14+ isomeric state. Due to limited spectroscopic information, the > spins and parities for the levels above this isomer are tentative.The structure of Ta-182 and Ta-183 are also investigated by comparing the measured transition strengths with similar transitions in the mass region. Most of the transition strengths measured are in good agreement with expectations in the region, except for a few cases of E1 decays that are anomalous. Possible explanations for some of these anomalous transition strengths have been discussed.Few cases has been observed where the predicted yrast states are not observed experimental in both Ta-182 and Ta-183. Possible explanations have been discussed as well.Both the calculations and experimental results suggest a high density of intrinsic states occurs along the yrast line at high excitation energy in both nuclei. This pattern seems to emerge in the more neutron-rich tantalums isotopes resulting in a more complex level scheme that is difficult to interpret.

Available in PDF, EPUB and Kindle. Book excerpt: "Radioactive Xenon was produced by proton bombardment of LiI at selected proton energies up to 85 Mev in the 84" synchrocyclotron at McGill. Sources were prepared by imbedding the Xenon in the cooled aluminum cathode of a direct current discharge tube. Xenon of mass numbers 125, 123, 122, 121 has been studied. In addition the positron spectrum of I122 and electron conversion lines arising from the decay of I123 and I121 have been measured." --
