摘要：
We have investigated the effects of scattering and absorption in neutron beam activation analysis experiments, both by direct measurement and by Monte Carlo simulation. Significant sensitivity enhancements occur for thin disks placed at 45-degrees to the beam but very much smaller effects occur for spheres. The agreement between measurement and calculation is generally good.
