Abstract

We have obtained charge-changing cross sections and partial cross sections for fragmentation of 1.05 GeV/nucleon Fe projectiles incident on H, C, Al, Cu, and Pb nuclei. The energy region covered by this experiment is critical for an understanding of galactic cosmic ray propagation and space radiation biophysics. Surviving primary beam particles and fragments with charges from 12 to 25 produced within a forward cone of half-angle 61 mrad were detected using a silicon detector telescope to identify their charge and the cross sections were calculated after correction of the measured yields for finite target thickness effects. The cross sections are compared to model calculations and to previous measurements. Cross sections for the production of fragments with even-numbered nuclear charges are seen to be enhanced in almost all cases.

  • Using measured cross sections, the nuclear mean free path of an iron ion is only about 12 g/cm2, roughly half of the typical vertical column depth at Gale Crater.

    “For instance, using measured cross sections (Zeitlin et al. 1997), the nuclear mean free path of an iron ion is only about 12 g/ cm 2 , roughly half of the typical vertical column depth at Gale Crater.”

    From Radiation environment for future human exploration on the surface of Mars: the current understanding based on MSL/RAD dose measurements (2021) · cites this paper as Zeitlin et al. 1997

    Table 1 (page unavailable) reports measured charge-changing cross sections for iron ions on several targets, supporting the cited basis for a mean-free-path calculation. The paper does not state a mean free path of about 12 g/cm² or calculate one for the atmosphere; it also gives no Gale Crater column depth. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
