Measurements of Cl-36 in Antarctic meteorites and Antarctic ice using a Van de Graaff accelerator
The paper presents measurements of cosmic-ray produced (Cl-36) in Antarctic meteorites and ice using a Van de Graaff accelerator as an ultrasensitive mass spectrometer. Results from this ion counting technique are used to support a two-stage irradiation model for the Yamato-7301 and Allan Hills-7600...
