3He, 20,21,22Ne, 14C, 10Be, 26Al, and 36Cl in magnetic fractions
We report on studies of the concentrations of cosmogenic nuclides in the magnetic fraction of cosmic dust particles recovered from the South Pole Water Well (SPWW) and from Greenland. Our results confirm that cosmic dust material from these locations contains measurable amounts of cosmogenic nuclide...
