Abstract

The production rates of nuclides made by the galactic and solar cosmic rays are important in the interpretations of measurements made with lunar samples, meteorites, and cosmic spherules. Production rates of cosmogenic nuclides have been predicted by a variety of methods that are reviewed in this paper, ranging from systematic studies of one or a group of meteorites to purely theoretical calculations. Production rates can vary with the chemical composition and the preatmospheric depth of the sample and with the size and shape of the object. While the production systematics for cosmogenic nuclides are fairly well known, our ability to predict their production rates can be improved, with a corresponding increase in the scientific return. Additional detailed studies of cosmogenic nuclides in extraterrestrial objects are needed, especially for fairly small and very large objects. Nuclides made in simulation experiments and cross sections for many major nuclear reactions should be measured. Such studies are especially needed for the long-lived radionuclides that have only recently become readily measurable by accelerator mass spectrometry. 34 refs., 5 figs.

Production systematics of cosmogenic nuclides in the earth

Conference Reedy, R

The high-energy particles in the galactic cosmic rays, (GCR) can produce nuclides deep in any object exposed to them. These cosmic-ray-produced (cosmogenic) nuclides have been extensively studied during the last four decades, mainly in meteorites and lunar samples (e.g., 1,2). In extraterrestrial matter, several approaches have been used to determine the production systematics of these cosmogenic nuclides. Production rates of most cosmogenic nuclides in the Earth axe much lower, especially those nuclides made ``in situ`` in the Earth`s surface. Many of these @trial cosmogenic nuclides are only now being measured because of improved techniques, such as accelerator mass spectrometry (AMS).more »« less

Cosmic-ray interactions and dating of meteorite stranding surfaces with cosmogenic nuclides

Conference Reedy, R

A wide variety of products from cosmic-ray interactions have been measured in terrestrial or extraterrestrial samples. These ''cosmogenic'' products include radiation damage tracks and rare nuclides that are made by nuclear reactions. They often have been used to determine the fluxes and composition of cosmic-ray particles in the past, but they are usually used to study the history of the ''target'' (such as the time period that it was exposed to cosmic-ray particles). Products made by both the high-energy galactic cosmic rays and energetic particles emitted irregularly from the Sun have been extensively studied. Some of these cosmogenic products, especiallymore »« less

Spallation reactions in extraterrestrial matter

Journal Article Michel, Rolf - AIP Conference Proceedings

This paper describes the cosmic-ray-induced production of stable and radioactive residual nuclides, the so-called cosmogenic nuclides. In extraterrestrial solar-system matter, i.e. planetary surfaces, meteorites, cosmic dust and the heavy component of the galactic cosmic radiation, these nuclides are experimentally observable as positive anomalies of isotopic abundances. They preserve a record of cosmic ray exposure which can be interpreted with respect to the collision and exposure history of the irradiated objects as well as to intensities and spectral distributions of cosmic ray particles in the past. To decipher the cosmic ray record in extraterrestrial matter and to obtain information which cannotmore »« less

Model for GCR-particle fluxes in stony meteorites and production rates of cosmogenic nuclides

Journal Article Reedy, R - J. Geophys. Res.; (United States)

A model is presented for the differential fluxes of galactic cosmic ray (GCR) particles with energies above 1 MeV inside any spherical stony meteorite as a function of the meteorite's preatmospheric radius and the samples's depth. This model is based on the Reedy-Arnold equations for the energy-dependent fluxes of GCR particles in the moon and is an extension of flux parameters that were derived for several meteorites of various sizes. This flux model is used to calculate the production rates of many cosmogenic nuclides as a function of radius and depth. The peak production rates for most nuclides that aremore »« less
