摘要：

Instrumental neutron activation analysis and neutron activation analysis with a high-resolution lithium-drifted germanium detector, chemical group separations, and a coincidence-anticoincidence system were used to determine 45 elements in U. S. Geological Survey standard rock samples BCR-1, AGV-1, and G-2. U. S. Geological Survey standard rock W-1 was used as the standard. The principal nuclides, their γ-rays used in the determinations, and the best time after irradiation for counting are listed. Nuclides are separated chemically into groups for counting by volatilization, extraction with hydrated antimony pentoxide, ion exchange, and solvent extraction with TBP. Agreement of our results with published data is good. © 1969, American Chemical Society. All rights reserved.
