Download or read book Measurement of Cross Sections for Alpha induced Reactions on 197Au and Thick target Yields for the alpha gamma Process on 64Zn and 63Cu written by and published by . This book was released on 2006 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured the cross sections for the 197Au([alpha], [gamma])2°1Tl and 197Au([alpha],2n)199Tl reactions in the 17.9- to 23.9-MeV energy range, and 197Au([alpha], n)2°°Tl reaction in the 13.4- to 23.9-MeV energy range using an activation technique. Thick-target yields for the 64Zn([alpha], [gamma])68Ge (7- to 14-MeV) and 63Cu([alpha], [gamma])67Ga (7-MeV) reactions were measured. For all measurements, natural elements were bombarded with He beams from the 88'' Cyclotron at the Lawrence Berkeley National Laboratory (LBNL). Irradiated samples were counted using a g-spectrometry system at LBNL's Low Background Facility. Measured 197Au([alpha], [gamma])2°1Tl cross-sections were compared with the NON-SMOKER theoretical values. The thick-target yields for the 64Zn([alpha], [gamma])68Ge and 63Cu([alpha], [gamma])67Ga reactions are also compared with the theoretical yield, calculated numerically using the energy dependent NON-SMOKER cross section data. In both cases, measured values are found to follow a trend of overlapping the predicted value near the alpha nucleus barrier height and fall below with a slowly widening difference between them in the sub barrier energy points.

Download or read book Thick Target Measurement of the 40Ca alpha Gamma 44Ti Reaction Rate written by and published by . This book was released on 2009 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thick-target yield for the 4°Ca(?,?)44Ti reaction has been measured for E{sub beam} = 4.13, 4.54, and 5.36 MeV using both an activation measurement and online?-ray spectroscopy. The results of the two measurements agree. From the measured yield a reaction rate is deduced that is smaller than statistical model calculations. This implies a smaller 44Ti production in supernova compared to recently measured 4°Ca(?,?)44Ti reaction rates.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured cross sections for the 63Cu(alpha, gamma)67Ga reaction in the 5.9-8.7 MeV energy range using an activation technique. Natural Cu foils were bombarded with alpha beams from the 88 Cyclotron at Lawrence Berkeley National Laboratory (LBNL). Activated foils were counted using gamma spectrometry system at LBNL's Low Background Facility. The 63Cu(alpha, gamma)67Ga cross-sections were determined and compared with the latest NON-SMOKER theoretical values. Experimental cross sections were found to be in agreement with theoretical values.

Book excerpt: Cross sections have been measured for the 1°7Ag([alpha], [gamma])111In reaction at several a-particle energies between 7.8 MeV and 11.9 MeV. This reaction is of interest because it can provide a check on calculations of low-energy ([alpha], [gamma]) cross sections required for stellar nucleosynthesis predictions. Stacks of natural Ag foils of 1 mm thickness and 99.97% purity were bombarded with 4He beams. Following irradiation, the yields of the 171-keV and 245-keV photons produced in the 2.805 day electron-capture decay of the 111In product nucleus were measured off-line. The Ag foils were interleaved with 99.6% purity, 6 [mu]m thick natural Ti foils so that known cross sections for the 48Ti([alpha], n) reaction could be used to check the accuracy of the beam current integration. For any given beam energy, beam energy degradation in the foils resulted in lower effective bombarding energies for successive foils in the stack, enabling measurements to be made for several energies per irradiation. The measured cross sections are compared with published statistical-model calculations.

Download or read book Neutron Generators for Analytical Purposes written by International Atomic Energy Agency and published by IAEA Radiation Technology Repo. This book was released on 2012 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.

Available in PDF, EPUB and Kindle. Book excerpt: This detailed and comprehensive reference to spallation -- from the foundations to the latest applications is the only work of its kind and is written by two internationally renowned researchers. Clearly divided into three parts, it begins with the basic principles, while the second part describes the proton-nucleus and proton-matter experiments so-called thin and thick target experiments in terms of secondary particle production as hadrons, pions, muons, photons, electrons, light and intermediate masses, isotope production, heating and energy deposition and materials damage. Many of the experiments are associated with studies, investigations and the construction of spallation neutron sources since 1975 with emphasis on the most recent developments. The final part on technology and applications describes the various engineering problems associated with high intensity neutron spallation sources, ATW's, the needed accelerator systems, material and neutron issues, and high energy neutron source shielding aspects. A must-have for engineers and physicists working in or entering this field.
