Scientific paper

The contents of spallogenic Mn-53 and target elements for its production were determined in 80- to 400-mg samples from 13 different locations of the LL6 chondrite St. Severin, along the 34.8-cm drill core AIII. The Mn-53 content increases from the surface to the center of the stone by approximately 30%. The variation with depth is described by several models, presuming that appropriate primary and secondary particle fluxes are chosen. The Mn-53 saturation activities are linearly correlated with the spallogenic He-3/Ne-21 and Ne-22/Ne-21 ratios, which suggests the possibility of eliminating uncertainties in the determination of Mn-53 cosmic ray exposure ages arising from depth effects and terrestrial residence times.
