Measurement of proton production cross sections of 10Be and 26Al from elements found in lunar rocks

Abstract

Proton production cross sections for 10Be, 26Al, 7Be and 22Na produced by protons in silicon dioxide (for oxygen) and silicon targets over a wide proton energy range, 25–500 MeV, have been measured using accelerator mass spectrometry or nondestructive γ-ray spectroscopy. These cross sections are important for interpreting measurements of the concentration of these nuclides produced in extraterrestrial materials by cosmic rays.
