摘要

The primary gamma rays and energy levels in Yb-174 were investigated in average resonance neutron capture using tailored neutron beams at 2 and 24 keV and a pair spectrometer at the High Flux Reactor at Brookhaven. A thermal neutron beam was also used. Nearly 300 levels with spin up to J = 4 are reported below 4 MeV. The distribution of radiative strength in this nucleus was derived and is analyzed with a giant dipole resonance and single-particle strength models. The neutron binding energy in Yb-174 was determined at 7464.4(3) keV. (c) 2005 Elsevier B.V All rights reserved.
