Neutron Capture Effects in Yamato-74191 and Rare Gas Composition in Yamato-75258
Results are summarized of mass spectrometrical measurements of rare gases in the Yamato-74191 (L3) chondrite. The rare gas compositions in the Yamato-75258 amphoterite (type 6) were measured. Spallogenic gases dominate in He and Ne. Cosmic-ray irradiation and gas retention ages were tentatively calc...
