PHOTONEUTRON CROSS SECTIONS FOR LANTHANUM AND PRASEODYMIUM

OSTI ID:4720534
The effect of shell closure on the photodisintegration giant resonance was investigated by measuring the ( gamma ,n) cross sections of lanthanum and praseodymium using the bremsstrahlung from the 70 Mev electron synchrotron. The photoneutron yield points were measured, at .5 Mev intervals from 8 to 30 Mev, using the Halpern-type detection system. The synchrotron beam was monitored by an ionization chamber calibrated to plus or minus 2%, also the neutron detection efficiency was calibrated by using a Ra-Be neutron source known to plus or minus 3%. The yield curve was determined
