Measurement of absolute intensities of some prompt gamma-lines from the Zr-91, Nd-143, Hf-177 and Sn-116,Sn-118-120,Sn-122,Sn-124(n, gamma) reactions and isomeric cross-sections of Sn-123m,Sn-125m by in-beam gamma-spectroscopy method

摘要

The previously unknown absolute intensities of 28 prompt gamma-rays from the thermal neutron capture in Zr-91, Nd-143, Hf-177 and Sn-116,Sn-118-120,Sn-122,Sn-124 were measured by an in-beam gamma-spectroscopy method at the WWR-M reactor (PNPI, Gatchina). Cross sections of the production of isomers Sn-123m,Sn-125m were also measured. (c) 2007 Elsevier Ltd. All rights reserved.
