CALCULATION OF A 'COSMIC RAY AGE' FOR THE IRON METEORITE 'CARBO'
The accuracy of the cosmic-ray age calculated from the potassium produced-by spallation depends principally upon how well the ratio of the formation cross sections for the potassium-40 and potassium-41 is known and the constancy of the cosmic-ray flux. The calculated age of 0.69 x 10/sup 9/ years agrees remarkably well with independent age determinations for this meteorite and other meteorites. (C.J.G.)
