A continuous flow vanadium bath has been used to measure the neutron yield from different accelerator targets, and the correction factors which have to be applied are discussed. The results of yield measurements for protons from 5 to 10 MeV on thick targets of Li, Be, Cu and Co are given and compared with calculated values. Based on these comparisons comments are made on the accuracy of the cross sections used in the yield calculations.

The energy distribution of the photoneutrons of NaD2O, InBe, LaBe and NaBe source systems were measured by means of a proton-recoil proportional counting tube. Spherical lead-shields of various thicknesses (ranging from 1·5 to 13 cm) were used to reduce the intense gamma field accompanying the neutron spectra to be measured. The spectra of spherical heterogeneous source arrangements for three different Be-target thicknesses (0·5, 1· and 2·0 cm) were measured and compared with the theoretical distribution as obtained by Monte-Carlo calculations. The change in spectrum shape due to the lead shields was also calculated by a Monte-Carlo routine. Good agreement between theoretical predictions and experimental results shows values for the peak of the neutron distribution of 264·1 ± 0·5 keV for the NaD2O system, 397·3 ± 0·8 keV for the InBe system, 761·7 ± 0·7 keV for the LaBe system, and 966·9 ± 0·5 keV for the NaBe source system. With the LaBe system a second neutron group of much lower intensity (6·5 per cent of the main group) could be found with a peak energy of 1097·5 +- 1·0 keV in good agreement to recent gamma-spectroscopic measurements.
