Cosmic-ray-produced helium in the Keen Mountain and Casas Grandes meteorites
Journal Article

· Journal of Geophysical Research
The He/sup 3/ and He/sup 4/ distributions were measured in the iron meteorites Keen Mountain and Casas Grandes. In the former, a small meteorite (6.75 kg), the He/sup 3/ and He/sup 4/ concentrations did not depend upon position. In the latter, a large meteorite (1550 kg), a "depth effect" was observed, and contours of constant He/sup 3/ and He/sup 4/ content could be drawn. An attempt is made to explain the results in terms of the model earlier presented in connection with similar work on the Grant meteorite.
