Measurements of spallation cross sections for 590 MeV protons on thin targets of copper, nickel, iron and aluminum

Abstract

Yields have been measured of approximately 50 spallation products from 590 MeV protons on thin natural targets of copper, nickel, iron and aluminum. Non-destructive γ-ray spectrographic techniques have been used in the analyses allowing yield determinations for the short-lived (i.e., T 1 2 ≧ 10 s ) spallation products. Measured yields are compared to yields calculated using the current formulae.
