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