Polymere chrom(III)-komplexe als folge der neutronenbestrahlung von kristallinem kaliumchromat — II Einfluß der bestrahlungsdauer auf die spezifische aktivität und diskussion der bildungsweise der ein- und mehrkernigen rückstoßprodukte

Abstract

The 51Cr activity distribution and the specific activity of the various mono- and polynuclear recoil products of chromium(III) produced by thermal neutron capture in crystalline K 2CrO 4 have been investigated as a function of neutron dose. For all neutron doses under investigation the highest enrichment factors for 51Cr have been observed in the fraction of the (presumably) trimeric complex. The enrichment factors for all cationic fractions decrease with increasing neutron dose. A mechanism for the formation of the mono- and polynuclear recoil products as a consequence of the n, γ-reaction in crystalline K 2CrO 4 is discussed.
