Cosmic Ray Production of 60Co in Double Beta Decay Source Materials
Norman, E. B.; Smith, A. R.; Barghouty, A. F.; Haight, R. C.; Wender, S. A.; Sep. 09, 2004; 8 pp.; In English Report No.(s): DE2005-15014801; UCRL-PROC-206435; No Copyright; Avail.: Department of Energy Information Bridge
An important background source in double beta-decay experiments is due to the presence of long-lived cosmogenic nuclides in the source materials. Cosmic-ray induced spallation reactions on medium to large mass nuclei can produce a wide range of radioisotopes. 60Co is a particularly challenging case because of its large total decay energy (2.824 MeV), its beta-decay endpoint energy (0.318 MeV), and its coincident photon rays at 1.173 and 1.332 MeV.
