Abstract
THE total neutron cross-sections of molybdenum and bromine have been measured between 0.05 and 10 eV. using a crystal spectrometer, and between 0.0025 and 0.1 eV. using a mechanical time-of-flight spectrometer. The crystal spectrometer is of the type described by Sturm1 using the (110) planes of a calcium fluoride crystal in transmission. The mechanical spectrometer is similar to the one described by Brill and Lichtenberger2. Both instruments use the Harwell pile as a source of neutrons.
