The two published literature values [Greenwood , Nucl. Phys. A252, 260 (1975) and Gelletly , J. Phys. G 11, 1055 (1985)] for absolute primary gamma intensities following thermal neutron capture of Yb-171 differ on average by a factor of 3. We have resolved this conflict in favor of Greenwood by a measurement of primary versus secondary intensities.
