Twenty-two angular C215900200008 distributions of the unresolved neutron groups were C215900200009 obtained, covering the energy range Ecm = 1.5 - 2.57 C215900200010 MeV in 60 keV steps. At most bombarding energies, C215900200011 differential cross sections for the neutrons were C215900200012 measured at Theta cm = 27, 58, 78, 99, 119 and 138 C215900200013 degrees. C215900200014 ANALYSIS (INTAD) The angular distributions were fitted with C215900200015 sum of Legendre polynomials. C215900200016 ERR-ANALYS (DATA-ERR) No information on sources of uncertainties.
