Abstract:
A new method for the determination of environmental Gd by neutron transmission (NT) experiments is proposed. The NT method is based on the measurements of neutron spectra passing through a target. From the attenuation of neutron spectra new data as concentration, width, resonance energies and cross section have been obtained.By a computer simulated experiment in a sample with 6 elements including 160Gd nucleus the concentration with an acceptable error lower than 10% was evaluated. Some other cases have been analyzed in order to improve the measurements. It was concluded that a combination of few analytical methods works well for the stable isotopes difficult to be determined by conventional neutron activation methods.
