Neutron capture cross sections have been measured for the nuclides Rb, Y, Nb, Cs, Ce, Gd and for the isotopes exp 155 Gd, exp 156 Gd, exp 157 Gd, exp 158 Gd and exp 160 Gd in the 0.5 MeV to 3.0 MeV neutron energy range. Absolute capture cross sections are determined by combining the technique used to study gamma-ray strength functions and the spectrum method of measuring partial neutron capture cross sections. The gamma rays are detected by a NaI scintillator surrounded by an annular NaI detector. Time-of-flight techniques are used to improve the signal-to-background ratio. Present results are compared with ENDF evaluations and with recent results obtained from statistical model calculations. (Atomindex citation 11:546305)
