FAST PHOTONEUTRONS FROM TANTALUM AND GOLD
The photonuclear cross sections for the prcduction of neutrons with energies greater than the Si/sup 28/(n,p)Al/sup 28/ threshold were determined for tantalum and gold from a maximum bremsstrahlung energy of 18 to 65 Mev. The integrated cross section to 65 Mev is about 800 Mev x mb for tantalum and 700 Mev x mb for gold. The fast neutron integrated cross section is compared with total neutron production cross section at several energies and is about 10% at all energies. (auth)
