| Abstract: | The nuclear and instrumental parameters for the determination of rare earth elements (REE) via thermal neutron capture prompt gamme-ray spectrometry are examined. Gamma-ray sensitivity tables adjusted for elemental abundance are presented. Only Gd and Sm can be readily measured in rocks with normal REE concentrations. Data are reported for 37 international reference samples. |
