Abstract: An existing McMaster University in vivo prompt gamma neutron activation analysis system has been improved in order to reduce the cadmium detection limit in the kidney and liver. The detection limit for the kidney was found to be 1.7mg, a greater than factor of 2 improvement over the previous results obtained at McMaster. The liver detection limit was determined to be 3.3ppm. The corresponding skin dose for these measurements was only 0.5mSv. The effect of kidney position on the detection limit also was examined. Figures of merit were calculated in order to compare the performance of the current system to others. [Copyright &y& Elsevier]

The fission of a variety of actinides was induced by fusion and transfer reactions between a 238 U beam and 12 C nuclei, in the active target MAYA. The performance of MAYA was studied, as well as its capability to reconstruct the fission-fragment trajectories. Furthermore, a full characterization of the different transfer reactions was achieved, and the populated excitation-energy distributions were investigated as a function of the kinetic energy in the entrance channel. The ratio between transfer- and fusion-induced fission cross-sections was also determined, in order to investigate the competition between both reaction types and its evolution with the incident energy. The experimental results will be discussed with a view to forthcoming radioactive-ion beam facilities, and next-generation active-target setups. [ABSTRACT FROM AUTHOR]
