COSMIC RAY EFFECTS FROM ASSAY OF HELIUM ISOTOPES

COSMIC RAY EFFECTS FROM ASSAY OF HELIUM ISOTOPES

A high-sensitivity mass spectrometer was developed. Samples of 10,000,000 atoms total can be analyzed. It was applied to measuring the spallation production of rare gas isotopes in foils exposed to cosmic radiation. Diffusion effects were studied and cross-sections measured.
