K. Sudarshan et al., Capture gamma-rays from Co-60 as multi gamma-ray efficiency standard for prompt gamma-ray neutron activation analysis, NUCL INST A, 457(1-2), 2001, pp. 180-186
The absolute emission probabilities of 49 gamma -rays from thermal neutron
capture in Co-59 were measured in the energy range of 150-7500 keV. Two ind
ependent approaches were used to arrive at the number of captured neutrons.
It has been proposed to use cobalt as a standard for absolute efficiency c
alibration of the detector over a wide energy range and as a suitable compa
rator in the k(0)-standardisation method of prompt gamma -ray neutron activ
ation analysis work. (C) 2001 Elsevier Science B.V. All rights reserved.
