Abstract

Re-examination of a vast amount of xenon isotope data which have been accumulated since the 1960s reveals that the so-called CCF (carbonaceous chondrite fission) xenon is a mixture of244Pu fission xenon and a severely mass-fractionated primordial xenon, whose isotopic composition has been further altered by neutron-capture and spallation reactions, which occurred in the vicinity of a supernova that most likely exploded sometime more than 4.8 billion years ago. The integrated flux of 10 KeV (stellar temperature) neutrons to which the xenon was exposed appears to have been in excess of 1023n/cm2.
