The photoneutron cross sections for ${\mathrm{I}}^{127}$ and ${\mathrm{Pr}}^{141}$ have been measured with about 170- and 320-keV photon energy resolution, using monoenergetic photons obtained from annihilation in flight of positrons. The ($\ensurema

The time behavior of delayed neutrons from the photofission of 238U and 235U was measured for bremsstrahlung endpoint energies of 8- and 10-MeV. The data were analyzed to determine the relative abu...

The energy spread of the photon line produced by annihilation of 15-MeV positrons in a thin LiH target has been measured. Positrons are produced by bombarding a Ta target with 10-MeV electrons from a linear accelerator. The positrons are accelerated

Continuously variable monochromatic gamma rays with an energy spread of 3% have been produced using the annihilation in flight of positrons accelerated in a linear electron accelerator. These gamma rays have been employed to measure the ($\ensuremath

The photoneutron cross sections of O/sup 16/ and Tb/sup 159/ were measured up to 30 Mlev using photons of 3% resolution resulting from positron annihilation-in-flight. Thirteen resonances corresponding to levels in O/sup 16/ were observed in the O/su
